Does this come under domestic violence?

I been married for 3 years and togeather for 5.i have 4 grown up children from previous relationship 3 of them have left home.i also have a 13 year old step daughter that as lived with me for the past 5 years.this man seemed like the best thing that had ever happened to me until about 12 months ago,i had a sterilisation reversal followed by 2 ectopic pregnancys,which left me with no tubes.this is when he started to be nasty.we decided to move 11 miles away from my family for a fresh start as he felt a bit jelious as his family were 150 miles away and his brothers and sisters in the carribean.after this things got even worse,he was giving me tasks to do of which i always tried my hardest because this man is my world,i got a full time job and worked long hours until i could no longer stand,as soon as i got home he would oftern make nasty comments which would make me cry,so i would go and sit in the bedroom alone for hours and cry,not one time did he ever come and comfort me.i had to finish my job as i was emotionally drained and could not focus at work.i was in big trouble for finishing as he said he thought we were going to save for ivf.at this time he did not have a job so my wage kept him and his daughter.now 3 months on he as found a excellent paid job he works seven days a week,but refuses to keep me.i have found a job myself just waiting for a start date.when he is home he gives me attention and tells me he loves me and cuddles me but as soon as he is at work i get nasty texts saying he wants a baby and always says things making out im in the wrong and so are my family even though i dont see none of them.im a good woman and oftern sit and cry and try to think what am i doing so wrong and everytime i get the same anwer,nothing as i see.the texts are upsetting and he just does not care.a few weeks ago we were invited to his nieces,baby christening,he left me home alone for 3 days,he ignored my texts and my calls.when he got home he told me he was glad he left me home as if he had taken me he would have come home the same day and said i would have been jelious because his women friends were hugging him up and swopping numbers.he said he wanted me to mix when we go his friends partys even though i dont know them.so i asked will it be ok to swop number with friends that i find,i was told no straight away because he says his male friends would want to take me away from him.when i ask if he wants a divorce he tells me no.he says he loves me lots but there is also occasions when he texts me and says he loves me a bit.i been thinking he is showing signs of a split personality,over the last weeks i found out he as been on a dating site,he told me he went to chat on there and nothing else he said he put on his status that he is married as soon as i found out he deleted it.he only goes to work and family partys so there is no doubt he is not cheating .he as refused to have with me for the past 2 weeks and tells me he feels its a waste of energy because he cannot get me pregnant and refuse.ive been told by a close friend he sounds very insecure and domineering.i am from the uk and he is from montserrat in the carribean.i love him so much but i cannot go on any advice plz.
