Relationship breaking down

Hi ladies! I was wondering on what you guys think I should do!!! Sooo here it goes:

I grew up in London and lived with my father for the 15 years of my life, my mother was a shadow in and out of my life for the most of it but hardly got on with my family...I moved to a hostel and managed to live on my own but was having difficulties with money at that age and never really had a good youth, I fell into a horrible relationship where the guy was very abusive towards me mentally and physically, I ended up leaving this guy but at the time met some other guy which was sweet and the complete opposite, I fell pregnant at 17 and felt alone, this guy ended up cheating on me in the end and I found out he was there only for a passport, at the time I was going to college and giving my son to a babysitter, I met this girl during college and she kind of introduced me to this guy who I instantly fell in love with...baring I’m mind I’m 27 now ladies....this guy took me and my then 5 month old baby, we couldn’t live a day without each other....he lived 4 hours away from London and I decided to move there too...the babies father wasn’t really bothered with the fact that he had a son and never really wanted to be in my sons life, so I started this new life with this guy and moved in with his family in there then fast food takeaway buisness, at that time I actually felt a taste of what family was all about...we used to wake up and prepare breakfast, lunch and dinner together as a big family and help run the buisness all the while my son was growing up know this guy as his father till today, me and my partner would argue during the first few years but this made us so strong together....we moved into our own home and I fell pregnant with my second baby ( a boy ) and felt like we where complete, this guys mother is so amazing she helped me raise these children as if they were her own kids...most of the time she has them as she assumed we needed that time together and as she knew my upbringing she wanted me to enjoy my youth with my partner so helped us out a lot of the kids....8 years pass and my partners father passes away and everyone decided to sell up and move back to London but at the time I had a permanent house and found it difficult to get a home swap to move closer to them so me and my partner carried on living the 4 hours away, this kind of put a strain on our relationship as my partner always wanted to be close to his family also, and he kept going back and forth to London, eventually I moved to London also but had to stay with his family for a good 2 years this made me and my partners relationship break down a bit more where we would just argue constantly and then have to look ok in front of his family as I’m not the type to argue in front of people, the kids have been staying with his mum for a while as we didn’t have a proper place to stay till this day we are struggling as the council have moved us into a hostel which is only a room with no washing machine etc, so the kids are there....long story short me and my partner of 10 years are at a breaking point where he is saying I’m a bad mother as I don’t wake up every morning to go and visit the kids and stay at his mothers during the whole day until he finishes work, our sex life is non existent where he complains every day and just today he has said I’m a bad mother and partner to him....he has broken up with me and I’m currently staying at his mothers house as she’s gone away for a few weeks and I need to be with the kids....I don’t know if he is 100% genuine with his words but it hurt...I also feel this relationship is not working out as we don’t have that same thing we used to have and I feel drained, I feel as if he expects to much from me or I’m just not doing what a normal partner should be doing, I totally understand him, but I just don’t know how to change as I feel as if we have gotten so lazy in this relationship with everything that there’s no way of changing things around, his mistakes are that his always been with friends a lot, he comes home late and this has been like this for years and we used to argue a lot about this that I’ve just given up, he never just surprises me and takes me places and is hardly romantic, and I always mention this but he always says because I’m not a proper partner to him, I feel as if he expects too much from me...so yeah his broken up with me now and I don’t know what to do as I’ve known him from such a young age I don’t know life without him, I don’t have family or friends to guide me and I feel so lonely...is there anyone in the same situation or know what I should do?
