It's never a problem, unless you are involved with a sociopathic narcissist. In that relationship, giving freely of yourself leaves you empty and wondering how you got so hurt. Give your life freely to those that deserve it, not demand it.
"There will be times in your life when you have to choose between being loved & being respected. Always pick being respected. That love without #respect was always fleeting but that respect could grow into real lasting #love." #quote
I have to constantly remind myself of this. Sometimes I have to force myself not to go above and beyond....keeps me from getting my feelings hurt by realizing not everyone is willing to do the same for me.
