Her friend

She's known this guy for about 8 years; the last 3 years of tht relationship she has been in an intimate relationship with him through high school and after. The relationship has been toxic with them doing things to hurt each other out of pettiness. After he ended the relationship she would still keep in contact with him and they would link for sex. At the time when her and I were just friends she had told me that if he wanted to get back together she would say yes. We've gotten to know each other over the past 4 months and we made things official in late September, we really lik each other and it shows. She has done a lot for me even taking interest in my religion.

While her and I were talking he did come back and asked to get back together. She turned him down but only after we had talked about it and I explained tht it is selfish to mak someone wait on you and it time to give another relationship a chance since he already had his. He texts her, calls her, and would show up to her house to talk to her. Even after being blocked he would find ways to talk to her by using family and friends numbers. He recently released that she is in a relationship with me but his behavior hasn't stopped.

She says I treat her better and that I can trust her because she wouldn't want to go back to that relationship. I went through her phone and she felt a type of way because that showed I didn't trust her as much as she thought. I only did it to understand the type of relationship they have.

They have been good friends before they were together so I know personally how it can be hard to cut someone lik that off. She still tries to be his friend but he makes it weird by questioning her lik he's still with her and bitchin when she doesn't call. I'm trying to be patient and understanding but I can't help to think about what he wants from her.

I've start writing in a journal so I can stop bugging out towards her about the situation but I need to hear others opinions.

He still asks to stop by and to talk to her while driving around. When asked if I can come along he gets mad and says no "anger issues". I trust her not to do anything with him but while she is jus trying to keep this friendship he's not acting lik a friend.

I don't know really how to handle this situation.
