How do you not feel trapped...

My baby is almost 8 months old. Been cosleeping since around 5 months when sleep training just wasn't for us. But I can't help but feel trapped now. Will I ever get to go out for dinner with friends again or have an evening to myself with my partner. He's EBF and wakes every 3 hours to feed still. I feel so isolated and alone and just stuck. He needs me right there to fall asleep and I try to sneak away to just go eat dinner but he wakes. I obviously love him and I want to be there for him as much as he needs but I feel so trapped and stuck like this will be forever. :( my first wasn't like this at all and I feel really blah about it.
