Here for help

My bf cheated on me. And I decided to stay with him. But I thought it was gonna be kinda easy to get things back but nope. He has change a lot but I’m just feeling down and depressive and I can’t deal with this no more. It’s like he killed my emotions. I was so happy before with him I would tell how great he was but now? It doesn’t feel right. And it’s hard. He is so happy we are getting a new house but guess what? I’m just like MEH and I know before I would be so happy. And we are TTC but guess what? I’m not telling him when its my fertile window cuz I don’t want to be pregnant and feeling this way. Has any of you go thru this? What’s my best option? And in the case to end this...how would you handle this?

Oh and in a side note...the lady who he cheated on me works with him. I checked his phone calls at AT&T.com; and it seems they don’t have calls or texts each other. And plus this lady knew about me and when I asked her she swear me in God’s name that nothing happened but my bf was the only who told me the true.

F me right?
