Pregnancy

Hi everyone, so I am 12 weeks pregnant and my ex decided to end the relationship while I was 11 weeks but he still supports me throughout the pregnancy. We have a set schedule of days that he comes over to my house but I’m still in my first trimester and I still feel sick most of the time * especially at night * so sometimes I feel like that schedule can’t necessarily work. Because some days he’s here I’m perfectly fine and other days he’s not here is when I need the most amount of support. Last night I had heartburn but before he went out with his friends he brought me some ice because I told him I wanted some but it was so hard for me to get up. He brought me the ice and still proceeded to go out. I don’t want to be the person who nags about him hanging out with his friends or going out but sometimes I just feel like it’s so unfair because I’m pregnant can’t do nothing and I feel sick most nights but he’s out having the time of his life until 1-2am. I don’t want to sound selfish but idk how to handle this situation. Can I get some advice please?
