I'm jealous

I wish I wasn't but I am. Everyone I know is getting engaged or are about to hit their wedding date and I'm over here wishing I had a promise ring from my SO. I'm always happy for my friends and people that I know or people who are having this happy occasion, I just wish sometimes I was a part of the joy. I just found out another friend of mine is newly engaged and expecting her 2nd child and I couldn't be happier for her but at the same time I envy her. I ask God to forgive me of my sin of envy (I'm Christian and it soothes me to pray) but I'm sorry I feel so envious. I hate feeling this way.
