I fucked up...

I feel like such an idiot. I had sex with my husband after hanging out with him only twice. Unlike a lot of the guys I did this with he surprisingly stuck around and ended up being the love of my life but I feel like I kind of cheated myself in a way by being such a ho. He didn't really try to woo me because he pretty much already had me from the start. Even though we ended up getting married, I still feel like I should have had more respect for myself. We didn't even go on our first proper days until we had been together for 6 months. He didn't get me anything for Christmas that first year and he never really buys me gifts or does anything romantic, even now. He didn't propose in a romantic way, he didn't even get on one knee and I already knew about it before hand because he pretty much told me he was going to do it. We got engaged in a hotel room after having sex. Now that we're married he definitely doesn't do anything romantic. I'm so mad at myself because in a way it's all my fault. How do I get my husband to try and "win me over" so to speak? I can't withhold sex and act uninterested because I'm afraid he would think that I don't love him or that I'm cheating on him or something. I don't know what to do.
