@lisa1471,
Instead of being sarcastic, how about thinking about it? It's actually a very good suggestion. If you can't trust the guy, or think he's messing with your head, then might as well find out now instead of letting it drag on and creeping you out.
Seriously, if you can't talk to him about what's bothering you then it's not any kind of relationship.
And if you don't want advice, don't ask.
