she could never have sex again because she just never really desires it.
Thats not a red flag, thats a statement of low sex drive, people must have matching sex drives in a relationship otherwise it causes problems, she was being honest and she needs a man who has low sex drive to. Get some maturity!
We had sex multiple times a week
thats normal at the start of a relationship, she might even be just doing it to get you in to a relationship but soon her low sex drive shows through.
and we ended up basically having to live together for about a month after only being together for a month.
Explain, why did this happen?
was super helpful to her and her family. I gave her rides everywhere and took care of her little brother.
Don't do this. Stick to your goals in life.
she had sex so much because she was trying to get me to commit to her
Bingo. just what i said above.
I told her I have no interest being with anyone that thinks that way and that she should leave. Fuck. Yes. I feel so much better.
Very honest but don't be too harsh. Its just a mismatch of sex drive and you're right to end the relationship. Understand she can't do anything to increase her sex drive than you can to decrease yours. Its neither of your faults. She wasn't honest at the beginning about her sex drive but thats what she feels she has to do to get a man, AWALT. Don't be mad at her, she might want less sex but on the plus side she wont be fucking chad behind your back, a very loyal home maker. She might also have a physcal reason shes not telling you, did she actually orgasm when you had sex?
how can I prevent this from happening in the future?
Find a slut ( you will need to be on it all the time) , or accept unicorns dont exist you always have to compromise something with a girl but if she has no red flags and worth LTR is having less sex something you can deal with, you can use escorts on the side, a lot of the top elite do this.
She told me she used to have sex with her ex she dated 3-5 times a week. Somehow she never wanted to touch me
A lot of girls are like this, people change. Young girls go through a horny period when they become sexually active from 13 to 20 then it really dies off after that, where as most men never bang enought women to get sexual desperation out of their system.
I'm a pretty damn good looking dude and have never ran into this issue before.
As said above different people different sex drives, people change, often sex drive is dependent a lot on the relationship dynamic.
Dude learn how to keep her in that "trying to get me to commit" phase. Don't move in together until at least a year or two, be elusive and aloof, let her be free to see no other guy compares to you, if you;re really all that she will still want you. Also see other girls. Use the concept of abundance. Get several plates, the one who steps up the most and fits you well will be the one you should LTR.
Borderline Personality Disorder. This girl has nearly every god damn symptom.
AWALT.
