Some anti-depressants don’t suppress libido or cause ED. Wellbutrin is one of them. Talk to your doctor about possibly switching to it or other options.
Just wanted to say as a teenager: having your parents together really isn’t that important to me. While they are still together, I think I would get by fine if my mom and dad split up. (assuming my dad got custody). Then again this is mainly because my mom is really cold and distant to everyone. Mommy issues aren’t fun. I haven’t noticed anything to screwed up in myself but I can see the effects in a lot of other people.
Don’t think that it will be the end of the world to your kids if you get a divorce.
