How do you know if a guy is sincere?
How do I know if a guy is sincere? I have been going out with my boyfriend for just about 3 months and I feel confused because he is 24 and I'm 20 and he has had a lot of experience with women and I've only had one boyfriend before him (actually an ex-fiancee)and my ex-fiancee began by being a good person, but turned into this controlling, manipulative guy, so I broke it off with him.
What scares me is that both of them share similar interests: they are both engineers, both like action movies, and both have similar personality quirks that make me feel scared that he is going to do the same things he did or make me feel the same way my ex-fiancee did... although of course he is a different person, I know that and I see it too, but I just feel wary of him and I almost feel like I can't trust him sometimes--is this normal? Will there ever be a time when I feel like I can trust him like I trust my best girlfriends? Should I trust him? Thanks
