Need advice

So me and my ex ended on good terms after a break up of 7 years . The reason why I broke up with him cause of how he neglected me when I was in a car accident and also becoming sick due to psychological stress and depression which caused me to not got my period for 3 months. He also avoided having sex with me . Expected me to still cook after working 3 jobs while exhausted. He didn’t celebrate my birthday for 5 years or ever gotten me flowers or did anything for Valentine’s Day. He also has a terrible gaming addiction which cause him one time to push me out the way when walking near the tv cause I was in his way. I can honestly go on with a long list of the things he done but the reason why I couldn’t leave the relationship sooner is because I have no family or friends I can go too stay with and he knew that me just took advantage of it. Last year I was finally able to move out and get my own apartment and life has been great since moving out but he called me last month and broke down apologizing to me for everything he’s done to me which I never thought he’ll do so I accept his apology and all and he asked if there ever be a chance to get back together I’m just like I barely even had time to heal from being in a relationship with you and why are you doing this now when I already moved on . I’ve have beg this man in past to work on our relationship when we were together and all I got was broken promises or he’ll watch a movie with me once a month then rush to the game so it was never any real quality time at all. So it pissed me off for him to even ask that so I asked him why are you begging for me now after you could’ve been changed like this isn’t fair at all and he explained himself which was just some bullshit reason honestly but I told I just want time to myself and don’t want a relationship with anyone right now. Then we continuing talking and ended on good terms. He started randomly cash app me money. And will also help get me groceries which I was very grateful for but I asked him like why are you doing this and he just said to help me out. We also talked on the phone often still cause he was going through things with his family. But we developed a great friendship, however yesterday we were going to the movies and when I got in the car he tells me to close my eyes and when I open my eyes there was a huge bouquet of flowers , a necklace and ice coffee in my head I’m just like I’m definitely getting love bomb right now cause how after we break up of 7 years you finally give me flowers and gifts but i just played it off and told him thank you and all that stuff. He even took me shopping and then before the movie he asked me about getting back together soon or whenever I’m ready and said he’ll wait for me and started talking about possibly moving in with him when he moves in a few months so we can “both” save more money, so right when he mentioned money I’m just like i definitely see why he’s doing all this , he wants that financial stability again cause I was paying for majority of the bills and rent when we lived together and also now that I’ve been getting back into paintings and making money off it and also getting into cosplaying soon , he wants to be involved with the money I make. So I just told him you’re overwhelming me honestly and he quickly said I know I just need you back and kept apologizing for everything. I have an unsettling gut feeling to not get back with him and it’s just the way he’s acting doesn’t feel genuine to me at all. I know part of it is my fault but I really wanted to see the movie long legs yesterday so that’s the main reason why I agreed to go to the movies and I know people can possibly change as well it’s just the way he instantly changed after breaking up with doesn’t sit right with me and honestly I feel like it’s just the love bombing technique or thinks I’m vulnerable enough cause I have no family in my life and need that security of someone being there with me which is just not the case. Everything was strictly friendly with him until yesterday and I have no interest on getting back with him either cause I’m just not attracted to him at all anymore I also told him when he talks about getting back together for acts all lovey dovey it stresses me out but he keeps saying he can’t help it or whatever. I don’t know what to do honestly cause I have a guilty mindset that if I do cut contact completely I’ll feel bad cause of all the money he spent yesterday and the flowers he gotten me but also don’t want to feel that way cause I feel he knows exactly what he’s doing and knows I have a good heart. The situation is definitely toxic but just need more advice or am I overthinking anything?
