My EX WIFE had those same issues. No libido and on Paxil for depression and anxiety. Ended up taking off on me 3 times till I told her to get out of my life. Anyway lol we did blood work and everything. Nothing found ever. No reason for the issues. Needless to say, I'm very against any woman taking antidepressants or mental meds from what happened to me.
Oh trust me dude I understand. It's been rocky at home for a long time to say the least, and it's taken abut everything I have to keep the marriage together. If it weren't for my kids it probably would have been over already.
I don't like her taking antidepressants. I'm against it myself, but recently I've seen what she is like without them, and there's no fucking way I can deal with that shit
