Marriage problems is it me?

hi please can anyone help me im a 39 year old lady with 4 grown up children of which 3 have left home so i only have the youngest one who is 14 at home.4 years ago i met a man who at the time was the man of my dreams,he was from montserrat in the carribean and im from the uk,not long after we met then 9 yr old daughter came to live with me and i took her on as my own daughter due to her natural mum disowning her due to a allegation she had made that was later proven that she was lying.a year later we married and everything was still ok,my family were local but my hubbys family lived approx 150 miles away so didnt get to see them oftern,but when i do go and visit his family i feel reall y uncomfortable and my hubby as picked up on it and doesnt want to take me with him no more which is causing us to argue,when i go visit his mum and dad hardly speak to me unless i start the conversation,my hubby is alwaysted ti given a plate of food if i want i have to have off his plate (my hubbys excuse was his parents wanted to see if i would eat there food ) which i think is a poor excuse,last time we went there to stay overnite we were expected to sleep on the floor with just a blanket and pillows we argued and came home the same day,his sister doesnt accept me i only ever met his sister one time when we first met,after that she never invited us there,my hubby goes to visit her when he is not with me,so that tells me something.in the past months i found out he as been on dating sites 2 times when i pulled him up over this he tells me that he had no intention of going behind my back it was just someone to talk to,what a joke.ive noticed that he as full movies stored to his phone and him and his work mate sit watching in there break times,when i tell him that doing this makes me feel useless,he says its a man thing and a woman should get involved in this.he tells me he really loves me loads but somtimes i make him unhappy and dont let him do what he want,he works all week and i look after his daughter i dont see none of his salary.he makes me feel like its me in the wrong when it is him.all my family have accepted him and love him to bits but i carnt pick up the phone to none of his family and have a chat as i hardly know them,i really love my hubby but just lately the way he is treating me i have the thought of cheating on him going through my head,thats what he is making me feel like.when i mention divorce he tells me is that all i ever come up with.i recently had a sterilisation and had 2 ectopic pregnancys with in 6 month and both tubes removed and not once did he cry or comfort me when i was going through it.please can some one advise me please maybe its because we are 2 different cultures i dont know what to think or do really,and i do not have anyone to advise me thanks x
