Resentment eating me up!!

My bf and i have been 2getha for 2 1/2 years, iam 23yrs and he is 33yrs old. I love him like the air i breathe but at times i can hate him.

When we first got 2getha he failed to mention the fact that he was still married. i found out and went livid but i had already fallen for him and he said that they were seperated for over 5 years - i forgave him and stayed with him in the hope that he would get his divorce.

A couple of months into the relationship i found out (through images on a phone i borrowed) that he was sleeping with his supposed to be separated- exwife a month after we met - once again i forgave him and tried to forget about it.

But every so often i bring it back up and question him again and we argue. I cant help it im not an arguementative person but im still hurting and felt cheated.

It is bad enough he has a 10year old daughter that he has full custody of and living with the both of us. But if i had known he was still maried and sleeping with the ex-wife i would have left well alone. I was 21 at the time and did not want no drama of baggage.

I resent him for having a daughter too. because of her we have only been out as a couple 5 times. (usualy out with friends or on my own) She is very possesive of her dad and is always competing with me for his attention. If i hug or kiss him she mirrors me and smirks. But she is a child so i ginore her and try and concentrate on being his girl.

I take the daughter to school and hour away by train and bus and come back home in time to have breakfast and get ready for work. Iam up at 6am and back home 9.30 and leaving the house at 11am for a 12pm start and sometimes a 9pm finish. And on the days iam working till 5.30 i come home and cook dinner.

And when my bf finishes work he eats and sleeps or goes tabl tennis. And iam begginig to really resent him. As i feel like an live in nanny and cook.

I resent him so badly and confessed this to him a couple of months ago when i went into my mood. He said that i have to either learn to forgive him and forget it of just call it a day.

I promised to try as i dont want to lose him but i cant help the way i feel. He's been promising to do the divorce for over 2years now and he says he needs the separation paperwork. His new excuse is the he cant find the paperwork and don't remeber where he and his ex signed the paperwork.

Maybe if he got his divorce and proved to me that that chapter in his life i s done. Where also trying for a baby and i have told him that if he aint divorced by the time i have the baby. My surname will be on the certificate.

Is it worth me staying with someone with so much baggae and who doesnt have the respect to divorce his ex-wife to prove his love for me? Should i be with someone my own age who can give me the attention i need?
