just looking for some advice

I don't know if I'm falling for depression or if I'm tripping but I honestly need advice I'm 18 years old my baby is about to be 2 months... my bf is 21 he helps me a little or when he cans ... I feel like he hasn't really spent time with us like just me and him and my daughter ever sense I came home from the hospital he brought his daughter I honestly I just wanted to rest and relax then next weekend comes by and he goes out with his friends then then week comes by and brings his daughter for a whole week , then this week comes by and he goes out again, he works all day everyday he only gets 2 days off when ever he has to go pick up his daughter but it seems like when he won't have her he will decide to go out again ( DONT GET ME WRONG I DONT HAVE NOTHING AGAINST HIS DAUGHTER OR ANYTHING I DO NOT CALL HER MY STEP DAUGHTER BC I JUST MEET HER A COUPLE OF MONTHS HE FINALLY GOT HER BACK SO ALL THIS IS NEW TO ME SHES A WONDERFUL LITTLE GIRL ) anyways I just feel like he doesn't want to spend time with us I feel like he would find someone else Bc he gets to go out and meet new people but I don't know if it's just me or if I should actually feel like this .
( do not judge me , no rude comments that's the least thing I need right now please )
