'My fiance keeps checking out other girls'

I have been engaged for six months and we are to get married within four months. The thing is, I am increasingly wary about my fiancé's behaviour because he always checks out other women whenever we are out together. He stares at them and sometimes comments about their bodies, which makes me very uncomfortable. It makes me feel as if he will cheat on me at some point, even though he hasn't done anything to arouse my suspicions while we have been together. Am I being paranoid?

I'm not sure what makes you believe he's going to cheat if he hasn't said or done anything to give you that impression yet. What I do believe is that his attention to other women makes you jealous to a certain extent. Yes, comments on their bodies are absolutely inexcusable, even though I assume he says these things because he assumes he can be comfortable enough with you to say them. It clearly bothers you though, and he needs to know this so he can draw a line somewhere. Tell him how you feel and why his attention to other women bothers you. If he cares about you, I'm pretty sure he will tone it down and stop those awful comments. As for your fears of him cheating on you at some point in the future, they don't make sense if he hasn't actually done anything to give you that indication. Commenting on other women doesn't necessarily mean he intends to get into a relationship with them and jeopardise his future with you.

My boyfriend insists I wear his favourite colours when we go out together. It's as if my opinion doesn't matter at all. Is he right to do this?
Your boyfriend is being an ass. You should wear anything you like, and in any colour, because it's your body, not his. Don't let someone thrust their likes upon you simply because they mistakenly believe they have a right to do so.
