He won’t take me on a date or buy me anything

My fiancé moved in with me 6 months ago. Since he moved in I have paid the bills, groceries, household needs, gas, his cigarettes, alcohol, and other stuff. I have paid for all the dates and when he wants something, I pay for it. He’s not a cheap person. When we go on dates, out to eat, or do anything he orders the most expensive thing. I don’t mind doing this because I love him and I want him to be happy and I enjoy doing for him. But I’m a single mom and I do have children that depend on me. It’s never been a problem, my bills are paid and my kids have what they need. But I’ve noticed that he sometimes complains that I buy my kids too much clothes. I won’t lie, my kids have 2 dressers, 2 closets, a tub, and 2 hampers full of clothes. I like for my kids to have stuff. Nothing is wasted, it’s all used. He makes comments about how I have no clothes, which is also true. My babies come first and I don’t think of myself very much. I feel like what I do with my kids is my business and I don’t think anyone needs to have an opinion on it. I’m taking care of my kids, that’s all that matters. What I have an issue with is that my fiancé does nothing for me. In the entire time we’ve been dating he’s only bought me one thing, a $20 necklace from the local pharmacy. It’s a cute leopard print cross necklace and I cherish it. I didn’t ask for it, he just got it for me and surprised me with it. I love the necklace. But that’s the only thing he’s ever gotten me. He’s never taken me on a date. When we go on dates, he takes my card and pays for it because he doesn’t like me paying for it. It makes him feel bad. But I don’t think he understands that no matter who’s swiping the card, I’m paying for it. I told him recently that he has to start paying bills. No excuses. He also has to help with groceries. He’s started helping with groceries and has paid one bill, the Wi-Fi bill. I told him today that he has to pay the gas, water and electricity. I pay for the rent and those utilities aren’t even 25% of what the rent is. He has no issue with paying the utilities and honestly I’m comfortable that arrangement, him paying those and me paying rent. My biggest issue is, today I was spring cleaning and found my old laptop. It has a Disk option on it and I got excited thinking my kids could watch movies on it when we’re on the road. But then when I tried to log in, it basically had reset and now I can’t get into it. Not a big deal but not a priority issue I plan on fixing anytime soon. Then today he tells me I should get it fixed so he can take it on the road with him for work and he can watch movies on it. I would have no issue with this except when he said it I instantly realized in my head that he hasn’t taken me on a date, he does nothing for me, his job doesn’t benefit me at all but he wants me to pay for a laptop to get fixed for him so he can use it. Not only that but he just expects me to do that. No. It’s my laptop and if it gets fixed my kids will be using it, not him. I didn’t respond back to him but I did ask him a few hours later when he plans on buying me flowers, taking me on a date, anything. And he said soon. But when I asked when’s soon? He just said soon. He’s gone for weeks at a time. I’ll see him one day a week every week. Let’s be real, I’m not going on a date anytime soon with him. He’s not getting me flowers. He said he took this traveling job for me because it pays well and he can “help more” but he’s been working for over a month and I haven’t seen a single benefit. Just a boyfriend who’s gone a lot. I don’t even care about the money, I care about the fact that he’s gone a ton and that he does nothing for me but expects everything from me. I love him but I’ll be honest I don’t see us getting married if this continues. I didn’t agree to a long distance relationship, I didn’t agree to be the only one doing this. When we first met he told me it was a “requirement” of his that his significant others do their part. “It has to be 100%-100%. No 50/50. We both have to give our all” but he doesn’t even give 50%. I love him, I love us, but like my best friend said today, how much of myself am I going to have to sacrifice to make him happy? When he won’t do the bare minimum for me. Flowers are literally $5 at the local grocery store. He can go out and buy himself whatever, like a $150 grease gun for his truck, but can’t spend $5 on me. And I’ve tried talking to him about this but he just gets mad everytime.
