To trust or not to trust my boyfriend?

[Ellie]

I can't say for certain whether or not you should trust him, but he probably deserves a chance to make things right with you. Sometimes people act stupidly without considering the consequences.

Tell him straightforwardly how you feel about this, and that it makes you uncomfortable when he makes sexual comments toward other women. It's not abnormal for guys to look at other attractive girls, but acting on it isn't acceptable (in most relationships anyway). Figure out where your limits are, and let him know. He should come to you first if something is wrong or he feels something is lacking, and sharing intimate details with strangers isn't ok. He should know exactly what your expectations are of him (and those expectations should include complete honesty), so that if something like this were to happen again, there would be no excuse.
