So a few months ago, my dad asked if i wanted to go to my cousins wedding in Ireland just after Christmas. He said it would be 2 days (28th, 29th). Since then me and my gf have wanted to spend more time together (she lives 2 hour train away from me), and when my mum told me she wanted to go to America for Christmas to see her family, and I probably couldn't come (i didn't mind anyway) I realised i could spend my first christmas away from my family. I get out of school on the 15th and have a train ticket for the 16th.
However, the last time she came down to where I live, both my parents caused a huge argument both trying to control me and pull me around, until eventually my dad kicked me out of his house, and I refused to stay at my mum's (she had been blackmailing my dad against me and lying to me, ruining half our holiday). On a phone call, while trying to talk to my dad about the situation (he was drunk as usual so not the best idea, but i had no choice), he ended up getting very angry and saying he would rip my head off and that i should sleep in the streets and he doesn't care.
Now he wants me to come to his for christmas and for the wedding which is actually 5 days (27th-2nd). Firstly, i don't like my Irish family (I lost respect when they support my dads choice of leaving my mum and refused to listen to what i had to say about him just because he's their family). Secondly, if i go the wedding, i have to leave my gf on the 24th (Christmas Eve!!!) and get less than half the time i would (a big deal since we don't get much time together). Thirdly, he was horrible and threatening to me previously and has not contacted my gf's parents saying that he will call the police if do not return on the 24th, so why would i want to spend time with him? He has previously been physically and (extremely) verbally abusive, and has caused me to self-harm.
I have done a lot of research and found that i am not legally obliged to stay at home if I am 16 or over (i am) and that you can not report a missing child unless you do not know their whereabouts, do not have communication with them, or do not know their state of living (e.g dead/alive). I have tried repeatedly to talk to my mum and dad (who are separated btw) and neither will budge on their opinions no matter how many points i make and how many of they points are rubbish.
At this point I am currently going to have to go to my gf, and not come back until my original planned date (2nd), completely ignoring my parents. The main problem is the police threat. It's stressing out my gf and her family which my parents have done before, and im really scared im causing them too much trouble. I'm considering either myself or telling my gf family to call the police and report harrassment, or at least talking to them about the situation, but im worried that will only cause more stress. My dad seems to want to continuously ruing my holidays and any chance i have to spend time with my gf, since ive recently started to actually want to be independent and not just a puppet for my parents.
One last thing that I've considered is moving out to her house, and switching colleges to the one she goes to. She has a big room we can share, and when I'm at her house I cook and clean my own clothes and even try to tidy their kitchen etc. And I would be willing to get a job and contribute to bills (I'm currently building my skills in programming and computing and I have a contact who said I could have a summer job or part time job soon if i learn C++). However this is terrifying to think about as up until the past few months, my relationship with my mum has been okay and I've been trying to maintain one with my dad, so leaving home and making such a big choice is very scary.
I have no idea what to do about this, do I call the police? do I leave home? It's crazy to think matters have escalated to this point all because i want to spend time with my girlfriend. My parents are just very controlling (especially my dad- neurotic, power freak whereas my mum just gets emotional). I know this is a long post but i needed to ask for help just for my sake. Any responses would be incredibly appreciated, and thank you so much to anyone who reads this. I'm sure i could go on much more, but I've tried to keep it to important details. Thanks again for reading!
