It's hard when an ex has made friends with family members in any situation. This might even be awkward for him. But he can't control what his family members do. If the internet sites (facebook) seems to be an issue on your end too, then what's the problem with getting rid of them? Has he gave you any reason not to trust him besides lying about cheating on his ex? And think about WHO told you that he did. She could be lying because she is jealous of you. There's three options you have:
1. Talk to him about the issues at hand. TRUST is very important in a relationship. Especially if you're away from him for long periods of time. Put the issues out there, tell him you're insecure about his ex.
2. Call it quits. If it's gotten too much for you.
3. Don't say anything. BUT, this will eventually become a HUGE problem and probably end the relationship.
Hope this helps.
