OP, listen up... You might not like what you hear.
Fact is this, no girl would feel comfortable throwing away someone they have feelings for. Period. If she can pull you in and throw you out at will, effortlessly, without a semblance of remorse, there are one of two likely scenarios at play.
One, she isn't feeling you in that way. I dont care what problems she has. Trust issues, love issues, daddy issues.... Them bullshyt excuses are a ploy. If a girl is
legitmately attracted to you, she will never be able to easily toss you away, if at all. Especially if you've done nothing wrong... She will try to make it work, try and keep you onboard. try to work through it. Remember that. We all got issues. But trust is no excuse for her taking you out like the trash every quarter of the year.
Which leads me to scenario two, which is the more likely case probably.
She dealing with someone else that she isnt telling you about. Someone she cares about more, more attracted to, more history with. Sure, she probably told you there is no one else, but there is... Not saying she a ho or anything, its just life...
