Am I a dick?

I’m honestly really confused and could use some outside opinions. There’s this girl I’ve been really close with, and over time we started getting closer. Eventually, we ended up making out, and while it felt good in the moment, afterward I had a lot of mixed feelings. A big part of this is that I’m really confused about my sexuality. I know I’m bisexual, but I’ve always pictured myself having a husband and kids someday, so it’s been hard for me to fully accept that I can also genuinely like girls. I’m still trying to figure out what I want and what my feelings actually mean. After we made out, I realized that while I care about her a lot, something about being romantic with her didn’t feel right to me. Because of that, I decided it would be better if we were just friends. I told her I care about her and still really want her in my life, but I don’t think I want to be in a relationship with her. I apologized because I know it probably hurt, especially since we had just made out. Now I feel really guilty and I’m wondering if I was a dick for doing that. I don’t want her to think I used her or led her on because that genuinely wasn’t my intention. I was just confused about my sexuality and my feelings, and making out with her honestly made me realize that I don’t think I have the romantic connection I thought I did.
