My ex took me to a really nice hotel to say goodbye, should I feel guilty for wanting to date?

We’ve been broken up for a year now but it’s never been longer than a month without seeing each other. He left because he told me he needed to get his life together be a better man and he hoped to marry me. He thought I’d end up cheating because he was self destructive. To an extent it’s true the grass started looking greener on the other side and I think he saw that so I regret my actions there.
Every 2-3 weeks I’d see him, it’s been an emotional rollercoaster and I’ve built up pain from the no commitment, and I was reliving the breakup and separation over and over.
Recently we met up again after a 3 month period, the longest we’ve gone and again it’s all play happy families.
I’ve reached a point where now I feel insecure and like am I just someone he says he hopes for a future but really he doesn’t see me as wife material. I don’t know what he gets up to when he’s not with me.
2 days after we’d already said goodbye again, he called me and said he’s got a beautiful villa for us his friend gave him half price and it’s the perfect way to say goodbye and I wanted to say no but he still has a hold on me so I ended up going. I was also his first relationship and first love.
I was happy but hurting at the same time. He said because before he didn’t have money to treat me, he wanted to have the opportunity to treat me before we part ways.
I get it but at the same time I’m giving him my body everything all to say goodbye. What am I supposed to do? Be loyal and wait on someone who may not be with me in the future, there is no promise it’s impossible to predict the future. However I now feel obliged not to date etc.

I met someone now who wants to date me, he’s really handsome, I admire and respect him. If my ex found out he’d be upset, he’d feel hurt if I was dating now because he’d think after what I just did for you and use it against me.
This breakup has been heavy and the situation has been confusing. I don’t know how to handle or view this
