Advice please?

Desiree

My boyfriends’ ex girlfriend has been kinda clingy still trying to get back with him. He’s told her over and over that he is with me and that he’s in love with me. About a month ago he called me by her name. We talked about it She called and they got into an argument. I forgive him because their relationship was 4 years. They had two dogs together, and lived together. She had the dogs, she was using them as an excuse to contact him. He blocked her on everything. He told her it is her problem to deal with the dogs. Today he called me by her name again. Both times was over the phone, I hung up. Apparently she stopped by his dads house yesterday. Should I believe that he hasn’t talked to her? What should I do? Our relationships long distance and he’s supposed to come see me next week.
