Hello, spaceid. This guy already has told you he does not understand the obsession with depression in the United States. He also flat out said he did not believe you when he asked about previous relationships. These comments are red flags for me.

My concern is if you continue to avoid discussing the mental health issues you are dealing with because you fear he will distance himself there may well be greater consequences for you down the road for failing to do so. I think you are better off being forthright now and risking his loss of interest than having him leave you after he has captured your heart. If you and he are able to work though his concerns after your disclosure, all the better.

As an aside, I suspect generalities about what most men think are really personal perceptions and may not be universally held. I say this because you mentioned your friend originally is from another country, which in my view make generalities even more unreliable in your situation.
