A way to indirectly diss my ex?

So I pretty much screwed myself over by dating my brother's friend. When we broke up, they still hung out. And you know how much drama travels from one person to another. So my ex started blaming me for several things that happened (which I can swear up and down was not my fault). Ever since he did that, he's been persistant to try and make me mad. After many failed attempts, he has finally come through and managed to piss me off. When he tried to convince a mutual friend of ours to not wear cowboy boots by saying "Who else wears em, who shouldnt, and kinda ruins the mental picture of em?". That was it, and I know he still likes me which is why he's so mad cause I don't like him back. At all. Well now I need to know a quote or just something to post on facebook(since I don't see him but once every week or 2) that disses him INDIRECTLY. Not to where it states his name. Just something to say I don't need his opinions and he means nothing to me. I really really appreciate this!! Thanks!
