I'm tired of how different my man acts when we're alone versus when we're with other people. In public it's like we're not even together--he'll want to hold my hand sometimes, but otherwise he rejects affection like we're just good buddies. The second it's just the two of us, though, he's all tender and sweet and affectionate--in a very physical way. Do you think this means he's embarrassed of me? Is he stringing me along? How do I get him to be more open about our relationship?
