so basically my me and my ex girlfriend (late 20s) have been in a horrible on and off again relationship. i know i should of never kept coming back to her and her coming back to me. but this weekend shit hit the fan. i picked her up at a party thinking she was in trouble, she texted "help" and found her out of her mind drunk.

on the way home she proceeded to... jerk the wheel, exclaiming that she is gonna get us both killed, kicked the window (front) multiple times (huge spider web crack covering half the passenger side of front window), punch me and scream at asking about everything we have ever argued about in the past.

at two points i attempted to forcibly remove her from my car and she kept jumping back in. she even got in the driver seat, to which i attempted to push her out from the passenger side. at one point i got her to her parents house and a neighbor yelled "hey!" which spooked us both and we ran into the car and drove away.

at one point she called my brother and said that i needed to be dealt with and he was at my house when we finally got home. i ran inside and declared i wanted nothing to do with her. this was about 4am. she was then picked up by a friend and was gone (from what my brother told her) then at 5am she entered my house with an extra key she secretly had made months ago, we had a whisper argument since my roommate was asleep. i told her to get to bed and i want her gone in the morning. then at around 7am i awoke to her being gone. at around 8am she returned again with money and said "see i told you i would pay" i took the money and demanded my key back. at that point i explained i had filled out an online restraining order (have to submit in person) and i will be filing it on tuesday (day off work) she pleaded and asked that i not. threatening me with "well if you do i will ruin you, i will spill all your secrets, i will place assault charges against you! remember...i bruise easily"

i slept the rest of the day, not even leaving my house.

Monday night i placed a police report naming her as the person who damaged my car and assaulted me (i have no bruises), i choose not to place any charges, and after conversing with my ex-social worker sister have decided not to submit the restraining order, not wanting to cause anymore trouble.

i feel powerless.... if i hit her back i would of been arrested for assault even if she hit me, if i left her on the side of the road and something bad happened i would feel like it was my fault, if the police were called during the two attempts the remove her it could of gotten really bad with all the angry energy flowing. i feel like i just have to suck it up. just like this whole relationship ive been having to. through all the emotional and physical abuse she put me though. she gets the last laugh :(
