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

My boyfriend of 1 years and 9 months and I have had a near perfect relationship, aside from me having jealousy issues. In the beginning of out relationship I didn't have much of a problem with him having female friends, until one of them started being a bitch to me. She kept saying negative things about me and tried suggesting that he breaks up with me, after that I stopped letting him have friends who are girls. He's now in a college course with this girl who he talks to, they text eachother and stuff. He lets me read through their conversations and it seems platonic, and he asked if he could hang out with her outside of the school, but I still have possessive feelings for him and don't know if I want him hanging out with another girl. I also don't want to seem controlling of him. Maybe I could let him but only if I'm there? What do you think I can do to handle this? Thanks :)
<bot>: I'm having issues with letting my boyfriend be friends with a girl. I've had negative experiences with that in the past and I'm not sure I feel like it's okay for him to be friends with her or not.
