It's a good idea. I've tried to take a close look at myself and be open about insecurities with my girlfriend, which is helping. I experience a previous long term relationship end with cheating, which I think clearly has stayed with me more than it should.

We actually went to a couples' therapist, where I explained that the problem was more mine but we were dealing with it together. We didn't love the pyschologist, so we're trying with another soon.
