Recently I’ve been talking to this boy. We’ve known each other since the beginning of the year when we met in our class. At the time he had a girlfriend, and we were pretty good friends. Fast forward a few months and him and his girlfriend break up after she cheated on him. Him and I started talking not long after (first just as friends, then it developed as more) and I told him I didn’t want him to feel rushed into anything and that we could take our time with a relationship.
The problem is, he still spends time with his ex. His family is really good friends with her, so they often see each other and hang out, and although he assured me nothings going to happen, it doesn’t sit well with me. They dated for almost three years, and it’s not easy to move on from someone like that. I told him them being friends didn’t bother me, because I didn’t want to come across as the jealous girl who always needs his attention, but in all honesty them being close does bother me. Am I crazy for being jealous? What should I tell him?

Tell him so you can work it out. Relationships are compromise. Also, you may want to meet her, so that you can see that she’s not actually a threat. I’m friends with a lot of my ex’s and their families. I just sent one’s mother who had cancer a care package. I’ve helped that some get dates and I honestly don’t feel the pang of jealousy, because I actually am a friend and moved on with my life as are they. Heck, most are friends of my husband too. (Not the high school ones. Those relationships were twenty years ago.) It comes down to trust. Right now in the early stages of a relationship you are right not to trust and keep a eye out for potential issues. But she may not be one. Meet her and follow your gut instincts.
