How do guys my age find real love again?

Me 59m, took 2 years to work on me. Decided to try and date again. Met a beautiful woman 54f and immediately hit it off. So sexually compatible it was scary. Allowed me to let the inner freak out. Anyway, 4 months in she say she feels smothered. Saw each other twice a week and barely, I mean barely texted or called at night. So we’re done because of my apparent insecurities, I will admit I’m a somewhat insecure person. I like or need the frequent reminder that I’m the one they want. Not to the point of exhaustion but it’s just my DNA, like it or not. It’s been 3 weeks and I cannot stop thinking of a woman that was only in my for 4 months. But it was really awesome. How do I move forward from this? I feel like I’ll never find my person. So discouraged at this age. Btw, I line in a large city in Texas and pickings here are slim for white females. Not being a dick but what I prefer so no negative racial comments please.
