Should I see him

So normally my fwb messages asking when I’m free to go over and sometimes I feel like I drop everything to go over and won’t message him because I don’t want to come across needy and all that🤦‍♀️. I messaged my fwb on Friday to see if I could go over on Saturday. He asked what time and I said around 5pm. He still lives at home and says I couldn’t stay over long he has uni work to do and dinner will be around 6 (takes me an hour to get to his), so I suggested for Sunday. He said it could work but will let me know on Saturday, he messages me at 10pm and says I can still go over if I want but he’s going out for a walk with a mate and then will be free. I messaged him today 2pm and asked when he’s free and he says later around 5. I told him to message when I should leave and I’ll see. Bc he always fks me over as he says a time and changes it when I say I’m leaving or I’ve left and I have to wait in my car. Should I still go over and get laid or just leave it.
