Leaving my fiance

So i have been with my fiance since may 2014. We talked for 3 months before we started dating and i got pregnant the first time i had sex with him. I had our first son feb 2015 and he proposed august 2015. Found out i was pregnant again with my second sept had him may 2016.

My fiance and i are not on good terms snymore. I dont feel in love with him at all anymore. I feel angry. I dont expect much or anything from him very rarely. But i have stepped up i always have his work clothes done i always have his dinner ready i do everything for him. He never ever ever surprises me with anything not even flowers. He always says o but i got you an engagement ring. I didnt ask for that he dod it on his own almost a year ago. That doesnt mean stop trying. We are due to wed aug 2017 but i am thibking of calling off the wedding. I do not feel in love anymore. I have tried to get him yo come have a bath with me and do little things but he doesnt.

Before i had kids i worked a very successful job i am pn mat leave and he expects mw to just be a stay at home.mom. but i want to aupport my family not only that but myself incase things dont work out.

I am really confused right now and i feel really upset and torn. Like what happened to us we were so in love and now we are lucky if we even have sex in a month. I never feel turned on by him. Is this a phase or am i actually not in love😟😔
