bf says he would fuck other girls

I dunno, I don't understand it, but I thought it was 19 and 28? I think it's bad enough when there's a young person with someone and there's a significant age difference, but when the older person is someone who doesn't have their shit together it's just awful. This guy is older than OP to the point where he should be setting a good example, and helping her out to get her shit together instead of mooching off his mommy and daddy, making OP feel jealous, insecure, talking casually about how he wants to sleep with other women and being verbally abusive to her.
