When tf say they don't love you

[Marie]

How can you get over that tf say they don't over you, want you, are through with you because you have problems and they're hurt, and then, when you talk, you sort it out and amends are made, then, they change the tune to they love you, wanna hold you, act like nothing ever happened!!! But they threw you to the bin! And what they said! And then, they are like it's as it was and they do things, and talk to you like they've never have a long time.
How do you get over that????? Would tf do that? Aren't they supposed to love you ANYWAY?
How can you get over they threw you to the bin when it didn't suit them and the problems could've should've been dealt with long tine before. Easily. How can you get over they quickly change to nothing happened all is like usual?????
