How do you get rid off someone's crush?

So my bf said he had feelings for someone while in a relationship with me. But he knows nothing of the sort will happen, but I just get really down by it. How can I help to make the situation better? Can my boyfriend lose his feelings completely and just be with me?

To be honest I'd be encouraged by the fact that he was open and honest with you about it.

People like to pretend that as soon as they're in a relationship they're completely blinded to anyone else of the opposite sex, but it's just not true. He may have felt attraction to someone else, its not that uncommon, but he still chose to stay with you. Take heart from that OP

Okay and do you know that if its normal for things like that to happen and just subside? I really don't want to lose him.

Absolutely, and if he's been talking with you about it then it sounds like he's already written it off and decided to leave it in the past.

I know its easier said than done, but try not to dwell on it too much - insecurity only causes problems in relationships, and he'll feel like you're punishing him for being honest with you.

I think nearly every real-life crush I've had has subsided. If he's been honest, I don't see why he won't get over it. People don't stop having crushes just because they're in a relationship.

I see.. and how would you distinguish feelings from crush? Same thing? Cos I think they are the same thing. So if my bf developed feelings for someone else, they're likely to go away right soon enough? we're LDR if that helps but see each other every few weeks. I'm just worried that his feelings don't get stronger if he hangs out with this girl...

I think a crush is more physical, nothing important. Having proper feelings is more than that, in my opinion.

You'll have to ask him what it actually was he felt. If it was merely physical, or emotional. Did he think she was hot, or want to actually date her?

He fell for my personality first then looks.
