<human>: If you check my previous posts you will see that I have had some serious issues with my ex.

I am f(23) he is m(25) and we were together for 2 years and 4 months.

At the beginning of our relationship he cheated on me. Two weeks later he told me he may or may not of cheated on me. He didn't remember, but he really didn't think he did it. I was swept up in my love for him and I trusted that someone who was my best friend for so long wouldn't do that to me.

A year goes by and it is eating away at me and I make him ask the chick if they had sex that night. She says they did. I have to try to deal with the pain of it.

We broke up because I discovered the other things I posted about.

Well now he tells me he wants to go to therapy and be completely honest with me.

He tells me he knew the entire time that he cheated on me, but that he didn't want me to find out later on, and be pissed that he never told me, and leave him, and he didn't want to tell me the truth because he didn't want me to leave him. So he stuck with the he may have had sex but isn't sure story.

I'm hurt so bad. His lies took away so much of my happiness.

He claims he is going to go to therapy and get better, and be better for me, but god damn it, I've just about had enough.

The person I thought he was, was the perfect person for me, but that person doesn't exist. Now I am tempted to wait and see if he becomes that person.

I am so lost and so confused.

Could you distill the essence of the text into 1-3 sentences?
<bot>: My ex lied to me about knowing that he cheated on me for over 2 years, throw in some other issues, and a promise of therapy, and my head is fucked.
