SHOULD I BE JEALOUS OF MY BOYFRIENDS BROTHERS BABY MOMMA?

**I apologize for this post being all over the place! Just venting**

I know that sounds weird but let me break it down...

So my bfs brother & his baby momma been together for 3 years before I met my boyfriend, so he knew her for 3 years+

The brother & her broke up because she was cheating with multiple guys, but they are still civil I guess for the baby. Before they broke up & the 3 of them used to hang out like 24/7 & party, now it’s just my boyfriend & I or my boyfriend & his brother... its never my boyfriend, his brother, & I ... so I think I might feel left out because my boyfriend knows his brothers ex well, but his brother doesn’t know me well... I sometimes feel like his brother doesn’t like me that much

My boyfriend of course loves his nephew but idk why but it’s almost as if I’m dating someone who has a child... because he talks about him all the time has his stuff at his apartment, EVEN has her movies at his apartment... uhm

I guess I kinda feel jealous because she was the first girl invited into their family and all the family members still lover her & I’m still new to them.

*** I know this was all over the place, I just needed to vent and let this out because idk why I find myself thing about this a lot :/
