Boyfriend problems!! Arghh

He's the one who cheated. He should learn to live without you and you should learn to live without him.

Why have you only started working less after you've broken up?

Anyway, he's got with one of your friends!! How on earth can you still be friends with her and consider getting back with him knowing that? Also, he didn't wait very long before moving on after you broke up..I wouldn't get back with him if I were you.

Very narrow minded thing to say.

When my ex and I broke up I slept with somebody else within a week, not because I didn't still love my ex (I did and frankly I was distraught for months) but because I was trying to get over her somehow, and in my state of mind sleeping around seemed like a reasonable way to do so.

tl;dr, People in love do crazy things.

Well that's my opinion..completely understand sleeping around to get over someone, but I don't understand why you'd sleep with their friend. That's just a line you don't cross. Surely, if you'd loved them that much you wouldn't want to potentially ruin their friendship as well?
My problem with it is the short amount of time, and the person they slept with. If he genuinely liked the friend, and had got with her a little while down the line then fine, but why use a friend as a rebound. It's just hurting her in 2 different ways.

Perhaps because he missed her and thus her friend was something of a "link" back to her? You're massively oversimplifying things and making the huge (and probably false) assumption that he was behaving rationally.

Edited to say I've seen your edit.

Maybe. Or maybe he fancied the friend all along, got with her and then regretted it?
Well, obviously I'm making assumptions because I don't know either of them and I'm oversimplifying things because sometimes when you're heartbroken you need to be (or need someone to be) objective.

Or maybe the friend fancied him all along and pounced while she had the chance (due to his emotional vulnerability)? That's essentially what happened to me.

I just think it would be silly to forego trying again over something that happened in the immediate fallout to a breakup, especially if both people claim to still love each other.
