what would you do?

my boyfriend and i have been together for 8 months, he moved in with me for 2 weeks then we had a fight and he left, we ended up getting back together… he works 4 days a week and my problem is i barely see him, his work days i can understand as he doesn’t finish till late at night but he has friday-sunday off and he always has to make plans to be “busy” on them days.. he says he’ll come see me but never does or it comes to the time and he starts complaining of “being tired” or “having a headache”…

for context, he’s 32 and im 22… i also have a 4 year old son that lives with me full time
