I took him back....was it a mistake?

Yes, you are stupid for taking him back. You aren't showing any respect for yourself and if you re-read you question closely you will see that you are allowing and even justifying his cheating. He didn't have a right to cheat on you because he had "needs". You don't need to hate him - you just need to love yourself and move on. Learn from this experience and say goodbye once and for all. You say yourself that you don't love him - don't worry about his "feelings". He has you believing that what he did was out of necessity which it wasn't. And then the fact that he didn't apologize. He is going to do it again. If the next "friend with benefits" decides she wants to become his girlfriend you will be dumped very quickly - probably not with even a phone call.

No you aren't stupid. Theirs no such thing as being stupid when you're following matters of the heart. seriously. people may look at it as being dumb, but if your relationship was important to you, and you forgave him, despite him not apologizing, then that's fine. You have to make the decision if you think he can handle a long distance relationship because without a doubt he will do it again. Are you okay with that? If not, then yea get out of it!

The fact that he hasn't apologized is huge. Unfortunately, when a person cheats it makes it really hard to continue on in the relationship. It's not necessarily impossible, it's just difficult. Not hating him is a good thing but it doesn't mean that you still want to be in a relationship with him. Life is too short to settle. I would say that you should think of whether or not this relationship is worth keeping on this level. You can still be his friend, you just don't necessarily have to date him.You're not stupid for taking him back.

Your not stupid for taking him back. Sometimes people make mistakes. But the fact that he didn't apologize is shitty of him. Often people don't love their boyfriends or girlfriends, but the question is, do you like him? Do you really like him? Because whether you take him back or not has to be on your terms and what is going to truly make you happy in the end.
