Me and my girlfriend has been together for almost 5 years now, I'm 29 and she's 27. She is bisexual and she has always wanted to have a kid.

Being a lesbian couple we decided to have one of our friend to be a sperm donor and have a kid with <a href="https://glowing.com/glow-fertility-program">IVF</a> (because it would be better than getting from a sperm bank). Our daughter is 11 months old and everything was okay until a couple months ago I notice that our friend and her has been talking on snapchat all the time.

I don't really use social media so I don't really know if this is normal. I work as a nurse and often work til late, and she's doing grad school. She usually spends time with our daughter and lately they both often hang out together with our daughter as well. Although I point out that I feel left out, she thought it would be a good idea for our daughter to have a good connection with her father.

I just feel like something is off, and they went out several times without telling me. I found out through friends who saw them together etc. They were never this close before, but I wonder if it's because of the child? Am I overreacting?
