Getn Abortion/BF wants to take his son away

I’m getting a medical abortion with the pill this Thursday. Then the second pill would be on Saturday the latest. My bf has been saying he will be there for me this whole time, now he wants to take his son away, with barely any money, cause his birthday is Monday. It’s a three hour car ride in the middle of NH. Considering all I’m going to be going through I don’t want to go and I don’t understand why he would think this is a good idea considering. I understand it’s his sons birthday but I’m literally having an abortion this same weekend. He said I could wait to take the second pill Sunday and I called him an idiot cause I’m not basing this around his little spoiled son who shouldn’t even be going away at all cause he’s been bad in school and at home. I told him what’s going to be happening and he still doesn’t get it. I told him I can go to the appt alone that if he’s not going to be all in I rather him not be there at all. Was I wrong for how I feel? I think he’s trying to avoid it all together and isn’t taking it seriously. Why would I want to be three hours away from home in a hotel room alone having my abortion with the 2nd pill. He will be with his son out and about. I rather be home and ALONE. He keeps calling me selfish and a bitch cause idc about his sons birthday but that’s honestly not what is important. He said he would be there for me for the whole process and now he clearly won’t be by his own decision.
