Rant

so i’ve been with my husband for the past two years and he has two beautiful boys and we have a baby girl together. well bio mom of his second boy (he’s almost 3), has never liked me since my husband and i have been together. meanwhile the first bio mom, my husband, and myself all have a cordial relationship with one another. anyways, it had been a year since we last saw his youngest son and we think it had to do with the fact that i was pregnant at the time and was just about to give birth to our daughter. (she hated the face that i was pregnant and even more knowing we were expecting a girl, weird i know.) but when we last saw him he had so much lice on his head and we were all upset (we know lice happens but this little boy had so many and his mom’s only solution was to shave his head). he also had so many cavities. just recently we finally got to see him (a whole year later) and the whole time prior to that the bio mom kept telling my husband, “he’s fine.” when my husband brought him home, he STILL had lice on his head and his cavities got so bad that some of his little teeth literally started decaying. my husband and i don’t know how to go about this because no matter how my husband expresses his concern over his son, bio mom will just try to argue and say something like “well i’m doing a good job and if you don’t think so then i’ll just never take him to you again.” we worry that she’s too focused on her social night life because my SIL still has her on social media and every weekend she’s always out and not with her son. she likes to use their son as a weapon against him if she doesn’t get what she wants (which is getting back together with him i wish i was joking). anyways sorry for the rant i just wish there was something we could do for this baby boy as his mom doesn’t seem to be doing the things she should for him.
