Search Results: my ex has a new boyfriend

Before we broke up, he moved to a new apartment and his new housemate is a female
She has a boyfriend but they dont live together
Even when we were still together, he would tell me everything she's says and does
So anyway, its been over 1 month since we broke up
But we still hang out together to movie, to special events, etc
He always tells me whats going on with him and his life
And he tells me about his housemate
He told me these things:
- he found out that she has herpes
- he said she asked if he wanted to hang out but he said "no"
- she would dress skanky and would always ask him "how do i look in this?" And he would tell her "why u asking me? Ask ur boyfriend"
- he would tell me thats she's stupid sometimes and attention seeking
And more things
Why does he tell me these things?
Is he interested in her?

My ex and me had a wonderful relationship. He was a very nice guy, kind to me, but he broke up with me after an argument. He has a new girlfriend now.

Yet, he often texts me. He sometimes sends a meme. Sometimes ask questions about me. But sometimes he gets really emotional. He tells me he'll never be happy again, that I'll marry my new boyfriend, that he'll never see me again and he can't accept that, he can't let me go, stuff like that. And then, he disappears. No texts. Then starts again. I ask him why he is doing this and he replies with "I don't know". I ask him if he really can't let me go and says "I don't know why I said that". Then few days later he texts again that our relationship was awesome and that our trip together is his best memory of his life.

What do you think of this behaviour? Also girls, I'm curious of your opinion too :)
