putting my big girl panties on

[flowmom]

Well, Guitarist ("boyfriend") is on vacation in a sunny place for 10 days. I'm feeling a bit triggered by seeing a gorgeous model posting this message on Guitarist's FB wall:

Funny stuff [Guitarist] today!!! You are awesome!
I'm waiting for my tacos in [location] now bouncing your tennis ball!!!! ((: thanx buddy!

Trust issues over here. It doesn't necessarily mean anything, but it just makes me want to run. I just don't want to feel vulnerable or give someone the power to betray me. Guitarist and I really don't know one another that well. I know the advice is to "go slow", but I'm not really sure what that means in practice, except not sleeping together, which apparently is not my strong point.

If he wants to flirt or more with other women...fine. I just want to know where I stand, especially since he's been the one pushing the envelope and wanting to "officially" "see one another".
