Yes, it would ... FOR YOU!
she's just not that into you, dude
cuz we all got a choice.. just like she chose not to love you back you can choose to get over it
If she can't, she can't...don't dwell on it, or you will become deranged and start stalking. Not a good scenario.
What you need is a source of steady sex, either from her or another woman. Then your question would be moot.
