My Father is an a**hole... Sorry for the long post

I really just need to vent at this point! My bio father and my mom divorced when I was 6 months old. My mom re-married (another a-hole) when I was 3 and they are still together (but this story isn't about him lol). My older sister has a different relationship with my bio dad bc she spent a few more years with him before my parents divorce. Growing up my dad lived an hour away so he would get my sister and I every other weekend. As we got older it was once a month, and then finally maybe meeting for dinner. My dad has always been a very selfish person even telling me once to "go to hell" because I didn't wish him a Happy Father's Day. So as I grew even older we grew further and further apart. He has moved to Florida and back (to Jersey) at least 5-6 times in the last 10 years. He happened to be living in the area when I was married in 2014 and as a wedding gift he wanted to pay for our photographer. He has never been one to spend money on me (I worked and earned my own money) but when he offered I said sure! So after we booked a photographer I told him how much it would be and he kept saying "I'll get it to you". Well instead of gifting us our photographer he decided he was going to move back to Florida 2 days after our wedding and that expense was more important. OK yes I was dissapointed and will never forget his promise but we moved on from it. Fast forward to 2016 he decided to move back to Jersey (yayy 😝). Since he moved back I've maybe seen him 3 times because he won't drive to visit me and my husband, we always have to go to him. This passed November my sister had my nephew (my dada first grandchild) and he refused to get a flu shot/whooping cough shot and my sister told him he would have to wait until January to see him then after the baby is vaccinated. My dad has yet to visit him. I am also pregnant and am due at the end of April with his first granddaughter. I got a text from him the other day telling me he's moving back to Florida (for good) in June. Since he refuses the flu shot I told him he may not get to see he granddaughter before he moves because she will not be vaccinated by the time he moves. He never responded to me after I told him that. I guess it just hurts that once again he chooses himself, but what makes this harder is now his grand children will suffer and not know their grandfather. He seems totally OK with this and it pisses me off! I know I'm better off without him in my life but it still hurts 😢...again sorry for the long rant just needed to vent ❤
