<human>: Can you provide a brief rundown of the text in within 3 sentences?

**Background**
Broke up with boyfriend after two weeks of him avoiding me, suspicious behaviour and generally him being quite neglectful. I also believed he was cheating on me as I asked him about his relationship with his ex and he proceeded to lie to me several times, denying their friendship etc. I also found two empty condom wrappers in his room. After 2 weeks of trying to communicate and see him, and him putting it off, I broke up with him.

(There is more to it than just this, but the full story is in my past submissions.)

**current situation**

It's been a rough few days, been flitting between feeling utterly rejected and questioning what it was that I've done wrong. Whilst I was out, I luckily didn't see him but in some kind of drunken stupour texted him asking if he did cheat on me, which he denied saying it was my "mistake for not trusting him". The more I think about it, the more I question whether I did the right thing breaking up with him, or if it I really did make a mistake in not trusting him. I've been questioning what it was that I did wrong and when I get into another relationship again how do I know what it was that I did wrong so I can learn from my mistakes. It's all just a bit of a mess at the moment.

I keep seeing and hearing little things I know he'd like, or find funny or interesting and I keep wondering "what's the harm in sending it to him?", which every time I have stopped myself from doing. But at the moment it's all so...difficult not speaking to him. What I find difficult is not knowing; not knowing how he is, not knowing what he's thinking about the break up, not knowing what it was that I have done wrong.
I wish I could just speak to him, and everything to be back the way it was before. But it's not. And it won't be. And I know I need to get over it, and deal with it all. But...I just don't know any more. I don't know if I did make the right decision, really.
<bot>: I don't know if breaking up was right. I don't know what I did wrong in the relationship. I miss him.
