Am I being selfish?!

I am a self-employed independent women who owns her own cars, things etc. I always end up dating guys who have not really made it in Life and I push them forward, motivate them and help them achieve their goals but in the end once they feel like they have made they turn around and backstab and hurt me. I promised myself no more will I date someone if I have to mother them, but I ended up falling for another again. I just feel like with my history of relationships it would be nice to be in a relationship where I am the one being spoiled and pushed and motivated for once, unfortunately my partner cannot afford to do those things for me and I just feel like I don't have the energy to do the mothering and always supporting financially which I cannot afford at the present moment. I am thinking of ending things, is it wrong of me? Am I being unreasonable?
