Fallen in love with my friends with benefits

I've accidentally fallen in love with my friends with benefits. In fact, I wouldn't even use the term "friends with benefits" because he only ever comes over for sex and when we text, 90% of it is sexting. We'll chat for a bit when he comes over, but that's it as far as non-sexual.

I never meant for it to be like this. But I can't bring myself to stop. Everytime he leaves my place I say to myself "That was the last time" but I just can't stop seeing him. I think about him almost all day everyday, and when I think about how he'll never feel the same way and how he could find someone serious at any minute, my heart breaks a little more.
I thought I could handle a casual relationship. But the way he always wants to cuddle, how nice he is in general and how good the sex is, it's just gotten to me, I think.

Does anyone have any advice for how to get over it and stop seeing him?

In your honest opinion, how do you think he feels about this? Do you think he has any feelings for you?
This is difficult because its not easy to speak to someone youre merely just in a sexual relationship with. What do you usually talk about when its non sexual?

If he is nice in general then maybe it wouldnt be a bad thing to talk to him about this. How do you think he'd react?

If I told him this, I think he would probably say that he was sorry for making me feel this way and probably stop seeing me.

I'm not entirely sure. We never really established what it was, but he said maybe 2 months ago that he wasn't looking for a girlfriend. When we talk about non-sexual things it's just a general chat about how I am and what I've been up to. He does say he misses me sometimes. He was also apparently disappointed when I said I was seeing other people and often asks me about other people I'm seeing.
But from the type of person he is I have a feeling he's just being polite. He said he doesn't want a girlfriend, and if he wanted me to be something more then he would ask me to do something with him that wasn't sexual. He'll never be over for more than 2 hours and he wouldn't start talking to me if it wasn't going to lead to sexting.

If I told him this, I think he would probably say that he was sorry for making me feel this way and probably stop seeing me.

What I put in bold- to me that suggets that some form of attachment has been formed, and there is an emotional bond there. That may sound obvious, but remember that he's only human and im sure hes had similar thoughts to you before.

The second bit in bold I'm not wholly convinced is true. Sometimes people don't act upon their feelings/thoughts. So dont be convinced that he's completely detached from you.
Hmm. This is a sticky situation isnt it? Do you see other people as in enter into relationships with others whilst sleeping with him?! I may have misinterpreted that, but I dont know what to say to that other than.. why?

So what do you want to do. Just continue a sexual relationship with him- or do you feel its not enough? Do you want to be with him? Are you willing to risk losing him by telling him how you feel?

I've slept with two people since seeing him, but neither of them led to anything. They were just one-offs. And the first guy was before I realised how I felt and with the second guy, I thought that seeing other people would keep the feels at bay (didn't work).
The last time I talked to him he hadn't seen anyone else but I don't know if this is still true.
I'm kind of okay with what we're doing at the moment, I'm just scared of him finding someone else and saying "I can't see you anymore, I've found someone special".

You have to be extremely careful how you do this but imo you have to tell him.

This will either lead to him having mutual feelings and a relationship starting or the FWB cutting off but you can't keep going on with it like this.

What do you mean by extremely careful?

Okay. Well i guess its up to you really. Like i say- is it worth risking losing him by telling him?

Well since I completely feel like there's no chance of him reciprocating I feel like I tell him and definitely lose him, don't tell him and keep him close while hurting all the time, or find a way to distance myself from him without telling him the real reason. But I really don't know what to do.

Why are you so convinced that these feelings arent reciprocated? You don't seem completely happy in this sexual relationship, so i wouldnt advise just accepting it and continuing the intimacy.

Well, these are all stupid reasons, but:
I think the main thing would be that he's 22 and starting his adult life with his full time job, as are his friends, and I'm only 19 and still in university, scrounging off my parents so I just feel like he wouldn't even bother with me.
I know this is kind of stupid and overthinking a lot but it's also his reluctance to kiss me that makes me feel like that? Kissing to me is a pretty important way of expressing feelings and we've never kissed with tongue, but recently he's been barely kissing me at all.
