Know clearly what is right and what is wrong and then have effective communication with him. Let him know u need ur space. Eitehr by action or by talk.
Make your ground and stick to it. Maybe tell him you need a gal's nite out a certain day of the week (u can go shpping, dining or watever) n then do tat. try to take time out for urself n eventually he'll realized or get in the habit of giving u space.
If u dont talk to him chances are u'll start hating him (which u said u laready have) n feel more suffocated. It's now or never.
Talk!! and ACT!!!!
Yes, indeed!
