How would you feel if you found out?

Well I would be glad that you could accept that you have a problem and do something about it. Hope your girl feels the same way =D

I would say that if you've gone on this far just fine when you had no idea he was on antidepressants, then it is not influencing who he is very much. So, you should just be glad that he opened up to you about this because obviously its something private that he only tells people he knows are trustworthy. I would almost take it as a compliment, because it seems like he is comfortable enough with you to take your relationship to the next level.

Everyone you ever dated or will date or will marry comes with some sort of baggage. Whether it be children, psycho ex's or depression. I would not mind as long as he told me the truth. It's if he hid it from me that would upset me. Or, if he came with a psycho ex that had his kids and he was on anti depressants! Lol.

It wouldn't be a big deal, and the amount of time it took for him to speak up about it wouldn't matter either. It's a very personal thing. So long as it's not affecting the relationship, why should it matter?

If you guys are good it is cool.
I might be a little hurt that he didn't let me in on it but if I loved them it wouldn't matter as long as they are happy.

I suggest talking with her in detail about why you are on them, and see how she feels about it. Maybe she will be able to help you so that you no longer need to take them.

I would only be upset if they tried to hide it from me. After a reasonable time, they should tell you, just in case you had a problem with it.

Most of Los Angeles is on anti-depressants. So it's no big deal to a lot of people, but apparently it is to you. How anyone other than you feels about it isn't really relevant.
