I’m a husband with pregnancy envy.

My wife has been off birth control for about a year now and we still can’t get pregnant. She is 36 and I am 35 and been married for 7 years. We had plans and wanted to wait a few years before we tried. My wife has been down and pessimistic about her fertility and feels it’s her fault (which I assure her, it’s not). I’m now at the point where I feel I am starting to feel pregnancy envy. I want to be a father so bad but I hear things every day that makes me jealous. My boss has a son and daughter and both of them are having their babies around the same time. I’m very happy for her and the family but this jealousy I am feeling keeps building to the point where hearing other people’s joy is just irritating. Has any one else felt this way? Thanks!
