I do not think you have problem. Your inability to win women heart with your money had nothing to do with your physical condition. The same problem goes for able bodied men, if you don't know.
Since you are not a cripple, I daresay that you are lucky to be getting women around you in spite of your condition. It only show that you problem has nothing to do with your leg, at least not 100%.
It is your attitude. You can't buy real love. If you do, It only last for as long as your money last. Should the lady get higher bidder, you would either have to raise the stake or lose out. That is the reality.
Intelligent ladies would feel insulted by that action. They would just treat you as 'mugu'. You have to understand that even blind men does get beautiful wives. In fact, this is real. Cripples also get spouses. It may be challenging, they do get there if they hold their heads high. Nature had never created a problem without solution.
My candid advice and the first step toward a new love chapter is to STOP THINKING MONEY ALONE CAN GET YOU TRUE LOVE. Don't let your disability be an escuse for dispair. Learn to love, people would reciprocate naturally. Don't give up. Just change your tactic, a good one would find you out.
we really need a clapping-emotion-smiley in here biko, because you just earned one!
That was very well said
@ olanajim 
Some guys think that with the presence of material things, all the other things that actually matter could be fed to the dogs!
@ posterThere's nothing wrong in pampering a girl, but don't do it for the wrong reasons.
Don't do it because you think you need it to cover your disability, and don't do it because you want her to stay by all means because you desperately need a girl . . do it because it comes naturally,
and do not over do it either, give her room to reciprocate the care and pampering . .too much of a one-sided love will sooner or later end up a disaster.
With that said, you sould try and weigh other aspects of the relationship . . could there be more to it than the pampering thingy, and minor deformity??
I mean could it be that there are other things you're not doing right??
olanajim was very right when he said that even people less financially stable and more physically wounded get beautiful girls, so no,i don't think thats the problem.
If it really was, there wouldnt have been a story of them not staying, because they wouldnt have been there in the first place

I strongly suggest you search yourself, and if you think deeply, i'm sure one or two of them that have walked out must have dropped behind the reason behind their sudden lack of interest in u and the relationship . . now that's what you should work on before going into another commitment, and always look for the girl of your choice, not a girl to make you feel better . . you deserve the best, because you're willing to give your best!!
Good luck oo . .
