How long have you been seeing her? When I first started dating my partner, he waited until we'd been seeing each other a little while and were 100% comfortable with each other before he brought it up. I'd been paranoid about what he thought about me because I knew he'd have seen my scars, so it was a relief to me that he reassured me that it was OK and that he was so understanding and supportive about it. It meant that when I was having a bad time, rather than dealing with it alone I knew that he would be there to help.
