Once again you are over thinking everything and not seeing this for what it really is.
First off, your ex treats you like crap!
Second, getting friends involved to help with business you should be taking care of yourself is both WEAK and DESPERATE.
Third, this fairy tail plan you have to attempt to "win her back" is absolutely ridiculous. I don't think I know one girl who would fall for this, and one guy who would even think this would work.
This "plan" you have is going to backfire. Yea, she will remember you for a long time, but for the wrong reason. Instead of remembering you as the one that she stupidly let go, she will remember you as the ex BF who was SO desperate to get her back that he gave her lame a$$ cashews and seashells!
I feel sorry for you bro. Not sorry for the fact that you're suffering from this loss, but the fact that you are attempting this lame plan to get someone back and making a fool of yourself at the same time.
For your sake, I hope you learn from this disaster and NEVER attempt something like this again.
