Broke up with ex, but he's giving me mixed signals

I broke up with my ex nearly 2 months ago, we were still having to live together up until 3 weeks ago. A few days before I moved out we got drunk and had sex, we agreed it was just a goodbye. After I moved out, he was still talking to me, wanting to see me and discussing as to why we broke up. I say him a couple of weeks ago, we didn't have sex again, we just talked. But after this he is still talking to me about life. He then brought up about us just having some fun for now, because he doesn't know how we can fix the relationship when our families are so against us getting back together, I for one make decision's on what I feel is best for me, my family know this about it me. So we got into the sexy talk over messages and agreed to meet up once he was back from working away, we are now a week later and he's dropped off the face of the earth, not answering my messages or anything I need advice because I'm really confused, and I don't like that one minute he wants me then the next he doesn't

Possibly, but this isn't fair on my feelings. Maybe ignoring him is the better option as I don't want to just have sex with him, that isn't what our relationship was or is to me

Yeah, it's not fair. But you've learned a valuable lesson.. when a guy says he wants to be friends with benefits. He really means FRIENDS with benefits. Nothing more. Definitely ignoring him would be best if that's not what you want. You need to look out for your own feelings.
