What could this mean?

Hey All,

So I’m on facebook and someone pops up on facebook.. Whatever. Its my boyfriends baby momma. I was just curious and clicked her page. Noooo I didn’t want to at all... Her page is open. So as I scroll down I see alot that she posts it mentions him (his name@ “ I remember how him and I did this or if she puts up a movie she’s watching she posted “ I remember when him and I watched this. I scroll more and all I see is she mentions him. They been apart 5 years ago........ Ive been with him 2 years..I kinda feel some type of way that she keeps mentioning/ posting about him now I wish I hadn’t looked. I scroll back to a few years ago lol same thing, grrrrr am I overreacting?!?! Anonymous post so leave a comment I won’t answer questions. 🚨 UPDATE- I’m know they have kids together and thats noooo problem at all. I’m saying he isnt even on her facebook as a friend. 🚨🚨🚨 And I have caught them talking at one point and it wasnt just about the kids she was telling him about how its hard for her to find a good guy. (This was a while ago). I’m feeling a type of way that she keeps posting about him. Thanks ladies I see she isn’t over him now ☺️ I have an ex as well and have kids together but i’m sorry i’m not going to mention my ex on fb about our memories since we have kids together. I respect my relationship and i’ll respect his.🚨🚨🚨🚨
