Am I destined to end up alone? Did I miss my chance on a good relationship?

I am 38 and was in a LTR for 15 years. That relationship did create two kids, however, I am a bit trapped. My ex is paralyzed and I have always taken care of her. We built a life together and even though it has been over for a year that we have officially ended it. I will always take care of her because I believe it's what is best for the kids, but I almost wonder if that just sabotages any potential relationship I may have. Most of my interactions with women are ones who just want money. While I am a traditional minded man, I am certainly not one to send money to someone I have never met. I am working extra hard to create what essentially is a parallel life because I want my woman to focus on the home front....I've tried all sorts of dating apps and have only been able to get one date. A large part of me wants to just say fuck it and buy myself a dirt bike, but I can't help but long for a woman to hold in my arms as we drift off to sleep at night. I'm pretty open to age range and have talked with women from 18 to 40. The common theme is the conversation typically becomes one sided and there's a lack of conversation engagement.

I believe that somewhere out there is a woman who would be infatuated with me in the same way that I am about her....but I wonder if I will ever find her.

I'm always around and do prefer to chat with women, but any fellow brothers out there looking to chat, feel free to reach out as well.
