October would make 4 years that I've been with my soon to be ex boyfriend, I don't think we'll make it till then. We're still together but barely. TTC for almost one year now & I was placed on metformin 2 months ago. It has been a struggle dealing with everyone else around me getting pregnant and me having trouble. Recently I found out that he had sex with someone else. I had intuition & knew something was going on but couldn't prove it. Since finding out I chose to stay and forgive him since we have so much history & being that I've been trying for so long with him to have a baby. Needless to say since finding that out I've been extremely insecure & have major trust issues. About a week ago I expressed my sorrow & depression to my "best friend" aka boyfriend about how being infertile is affecting me mentally through text message. It was a long message & I was waiting for a supportive & comfying reply but got silence instead. When I asked him about it his reason for not replying was that didn't have anything nice to say. My heart is literally broken & I don't know who he is anymore. I'm 25 years old & this is my first serious relationship. He's 35. I feel like this is the hardest decision that I have to make. But how do I get the strength to do what I need to do???????????????
