My boyfriend doesn't spend time with me anymore?

Thanks to the people who are reading this to try and help me out.
So I will begin:

I've started dating in university and wanted to know when do you know if the relationship is overdue for a breakup?
The reason I am asking this is because my boyfriend doesn't make effort to see me anymore, he's always been busy with work in general. But when we first dated, everything was like the honeymoon phase - it was perfect, we kept in contact, we spoke everyday - the usual.

Now onto a year and a bit...
He's oblivious, but our relationship has always been the same with no changes or plans to go out together. Is it harsh to say that I feel neglected? We don't communicate anymore, but there are the occasional I love you but whenever we meet in person it's bonded by lust.

Does anyone understand why someone would act like this?
If he's not interested in me that's okay, but I don't see the reason to drag out a relationship if the interest is already gone.

Neglected? Seriously? I dont blame the guy.

Have you both actually talked about this, he obviously doesn't realise, you both need to communicate with each other about all this.

Elaborate? You don't have to side with me, but I want to know why you say this.

I have been with my partner for 4 years, the first year is a FULL honeymoon phase, constant texting, constant love, the whole fairy tale beginning. After the first year it dies down abit, people think its because they dont love you or you dont love them anymore but its just the way relationships work, you become to comfortable in the relationship that you dont have to try constantly impress them. It takes two though! text him randomley saying you love him or you wana go for dinner or something! if you make the effort then at least you tried, if you still get nothing back then maybe it is the end unfortunately. every couple need attention, just depends on if their willing to give it, if not then find someone who will!

You feel neglected because you dont communicate as much as before, you seem too needy from what you have said which would put me off personally.

Yeah but...... say if you saw your girlfriend - once a month.
Would that be okay with you? and by saying that, you spend roughly 10-15 minutes during that time together. TBH, I don't think I'm that needy.

Why dont you communicate more with him?

If you're not happy with the way things are, talk to him about it. If he doesn't want to change you either put up or break up - it's up to you. Relationships mean different things to different people. Some might be perfectly happy the way you are, whereas others definitely wouldn't be.

You're right I don't need someone to be by my side 24/7, I just want to have a proper conversation every few days or so. That's really it, I wonder if I just expect too much from my SO.

I understand why you say this but yes, I also wonder if it's because I'm an extrovert and he's an introvert.
Thanks though
