First boyfriend as a single mum, please please advise

I am a 29 year old Single mum to a 6 year old and now im dating a 22 year old.guy who lives 200miles away. I was in an abusive relationship before meeting my partner

I met my boyfriend online in February and we got together the start of March. We met in person in May after being on video calls for the majority of the day apart from when I had work. He did work from home as a trader but the week or so before we did meet I sensed something was off as I was excited discussing plans and he wouldn't give the same energy. It got to the night before and called me up crying saying he is so sorry and I just said " your not coming are you " and he cried saying no and how he hates himself. That day he had told his family how his job as a trader was to an end atleast for now as financially it went bad and he was not without a job and wasn't able to afford to come up here. I was so eager to meet him that I offered and paid for over £80 for him to get the soonest train here so we could finally meet and he did. We've now been seeing eachother every weekend or every weekend and had times of being 4 weeks apart. With him living roughly 200miles away he has kept some underwear, shirts and shorts little bits here so he can have a change of clothes instead of always bringing it. I made room in my wardrobe and he slowly has been bringing more and more stuff up, I now do the laundry and ironing as well as I do the cooking alone or we do it together all while I am also caring for my 6 year old son at the same time. The housework falls on me but he does offer and does help with that too. It was so hard to balance giving my son attention and then giving him attention aswell without spreading myself too thin because I never get time alone. Between working and watching my son and video calls I don't get much or any quality time alone and the house if its messy gets on my nerves. I've come from a previous abusive relationship and that person is the father of my child, I have tried to explain to my new partner that I could tell him some not all of the bad things that I've been through so he can understands triggers, things that will have me panicked and understand more and he dismissed it and said he doesn't want to hear about any of that part of my life. I've met his mum and she is lovely, I've had him meet my parents too. I have butt heads with him over parental tips he's tried to provide with my child too as he wanted to take away all technology and go on an award system for him to earn everything he gets. Every week he goes home I feel worse, I cannot settle properly or be happy when he's here because I know soon he will be leaving again and I envy that he can do that while I'm going back to being just alone with my kid like old times. He has said he would move up here at some point but no further discussions have been made about that. He is younger than me I'm 29 and he is 22 nearly 23. I don't know why I'm not always fully fully happy with myself I'm always so stressed. I sound ungrateful. What do you advise ?
