Ok here is the rundown.....
E is supposed to see his dad every other weekend, his dad has a 1 year old daughter with someone else. This someone else is very selfish and really has no desire for my son to be around unless it is making her look good (like they will go somewhere fun for an hour for a photo op and spend the rest of the time parked in front of the couch, he didn't have a bed for months at their house, they feed him junk food until he literally throws up because "they don't know what he likes to eat" despite being literally given lists of foods, won't potty train him, etc). They also fight in front of E to the point that he begs them to call me to come pick him up and repeats to me things they have said (he's 3)
Bio dad and girlfriend are currently broken up for the 5 or 6 time in 2 years (they were not actually dating when she got pregnant, and didn't for the first months of her pregnancy because he wanted her to get an abortion). Girlfriend kicked him out of the house they are living in with her aunt and cousin an hour before he was supposed to pick E up for visitation about a month ago, and has not been there to bring her daughter to any of E's soccer games or really seen him since.
They have now decided to "work on their relationship" and want E to view them "as a family unit". I told Bio Dad I am not comfortable with this, that I don't want E in their issues, he has 26 days a month to "work on his relationship" and less than 4 full days a month with his son and that I think until they are officially back together they should not involve E in their desire to work things out because it is more confusing and upsetting for her to be around sometimes but not all the time, and for him to see them fighting. Am I being unreasonable?
