boyfriend in his 20’s, controlled by his step mom and biological father 😒

okay, i love my boyfriend and i’m getting very frustrated. so he has his own car and pays for the insurance and everything. he has a job. he’s a man. . if he asks his parents to come over my house he is put on a time limit. the most i get is 2-3 hours with him. when he has another day off of work and they say he’s not allowed to come over my house just for no reason, i have to wait a while till he has a day off of work AGAIN. since they don’t let him see me often he has to sneak and see me on his lunch break. i get 30 mins and then he has to get back to work on time. i appreciate it so much but it just sucks that i never get to see him yanno? he wants to move out and his parents are leaning toward the “NO” it’s very annoying when he’s in his 20’s and can’t do anything. they put a time limit EVEN WHEN HE’S GOING OUT BY HIMSELF TO LIKE GO BUY CLOTHES OR SOMETHING!!! his parents don’t even like him, they kick him out all the time when he’s such a great kid to them. he gives them money out of his pay check, buys his half siblings things (his parents too). so he sits home and watches his half brother and sister for them also. which is another reason why he can’t go anywhere because he’s forced to watch them. i know they’re his siblings but even after he’s watching them he can’t go ANYWHERE! OH AND his parents wanted to meet me a few weeks ago and when the time came, they used and excuse like “oh we’re cleaning the house” 🙄 and after that there were many occasions where i was supposed to meet them and his parents stood me up. there’s nothing i can do about any of this, there’s way more to how he’s treated badly by them.. and there’s way more to all of this.😞 i just wanted to vent because it’s overly aggravating...there’s so much that is wrong with all of this and i just don’t understand. it’s hurting me big time..
