You’re right. The problem isn’t that your boyfriend has seen other attractive women. The problem is that you don’t feel good enough about yourself. Although your head tells you that what’s important is who he loves, your insecurities tell you that he’s going to leave you any minute. This is not, not, not healthy for your relationship. In fact, your jealousy – and his – will probably result in the relationship ending. At some point, one of you is going to get sick of being controlled by the other.
You’re also right that you need counseling. Your school counselor, the school nurse, your pastor or rabbi, or your doctor can help you find one. There are often programs that offer free therapy to teens. In the meantime, if you need to talk to someone, please call the Boys and Girls Town Hotline. Counselors are there 24/7 to talk to teens who are in distress. Their number is: 800-448-3000.
I wish you well.
