What to do ?!

Hi ladies and gents if any are in this , so I have been with my bf for 2 years now and he goes out to bars/clubs as he pleases and half the time I don’t know he’s gone until I have to ask if he’s at home or me asking where he’s at after working 2nd shift And I’ve told him countless times I don’t like it and how I feel he should tell me so atleast I know where he’s at and it’s all the time now even during the week days and I just sit at home all night by myself and he never invites me to go only just a few times I went and everytime I do he finds a reason to argue with me even over nothing but he will find something, but he don’t let me go out or anything I can’t hardly do anything without him getting mad or being over bearing and had made me cut out a lot of my going out buddies saying they weren’t no good for me but I’m a whole wifey to him even though I’m just a gf and I clean, cook, help him with his 4 kids, and it’s like I’m never appreciated I do and do but he’s always telling me I need to work on this and that about myself but yet he never changes anything about himself even after I tell him how I feel at this point I’m just confused and mentally tired and physically I cater to him there for him 24/7 and work a 2nd shift job and pay bills and come hoke I never have a life like going out with friends or family just a simple run to Walmart he’s got to be on the phone with me but if he goes somewhere and I ask where he’s at or going half the time he gives me a attitude about it I’m just tired of not knowing what to do or how I should handle this situation ppl I have talk to just don’t understand what I’m going through so maybe some of y’all can help !! T.I.A!!!
