<human>: So my boyfriend (26/m)and I(27/f) have been dating for over a year now and we have had our ups and downs as any relationship. There's just one little thing that keeps occurring to me and bothering me that i can't get over. 
We both have friends of both genders, he has a chick best friend who has been nothing but nice and sweet and I get along with her well. The same goes on my side, I have male friends that he now hangs out with even without me which is awesome. 
So I met his mom a while back and have since gotten to know her and she's nice to me and she's sweet and I feel like we get along well. He's also the baby of the family and a little bit of a mamas boy.
The only awkward thing that happened is, well when we first started seeing each other it was casual and he had mentioned one drunken night where he and his female best friend had slept together. This was years ago and doesn't bother me. She's in a happy relationship now. He said his mom wanted the two of them to be a relationship because she gets along with her so well.
His mother is friends with myself and his female best friend on Facebook. She posts pictures of herself as anyone does on social media and his mom is constantly liking all her pictures and commenting how beautiful she is alllllllllll the time. Every picture. It's like she still wants to push the idea of them dating onto them even though she is happy with her boyfriend and my boyfriend and I are happy. I feel like it's becoming an awkward strain on our relationship because everytime we all go to her house or see her, she seems to make a huge deal out of how happy she is to see his best friend and merely gives me pleasantries when we're both present.
I've tried discussing it with my boyfriend and he thinks I'm overthinking it. What do you guys think?

Give me the gist of the text in a nutshell
<bot>: my boyfriends mom seems hung on the idea of him dating his female best friend even though she and I are both happy in our relationships and its awkward.
