Congratulations! To him!

So me nd my SO have been trying to get pregnant for a year to no avail, smh about 5 weeks ago or so he was caught having an affair nd we tried to work thru it very hard to do, but now his "mistress" advised him she's expecting!!!!!!! 💔 I think what's killing me is how bad we wanted a child! Now he's having it with someone else! I'm sure there's nothing to say but I need all the support in the world before I find a closet nd hang myself!! 😔
