Not sure where to post this...

So I’m a stepmom and I LOVE every minute of it!! He’s a little blessing of a two year old and I’m so happy to be ones of his mommies! My husband (2 year olds dad) and I are recently married and have been TTC for almost a year. I have pretty decent PCOS and struggle with my weight.. we’ve been disheartened at the multiple negative tests every month... I find myself sometimes getting jealous seeing him love on his son... I know I shouldn’t feel jealous but idk how else to feel... I give my ALL for these two boys and ALWAYS will! I just don’t know why I’m feeling this way- it’s like I get mad sometimes when I watch him being the best dad ever... please don’t think I’m crazy. I just want what he has with his son so bad it makes my heart hurt..
