Feeling lonely during pregnancy

I feel so lonely during my pregnancy so far (16 weeks) because my hubby’s lifestyle is still the same as pre-pregnancy e.g. goes out drinking almost daily, travels often for work. He’s great when we meet over the weekends (still waiting for bto) but I feel so selfish and clingy when I bring this up to him because I’m not sure what is the solution that would make us better. I know he’s trying to cope mentally with being a new dad too but I don’t want to look back at this pregnancy and only remember feeling sad and lonely. Did anyone experience this too and how did you deal with this?
