Been friends for so long but she's dating this new guy. He likes to get drunk start fights go off with the boys and appear home late. 12.30 at night to be exact when they had a flight the next morning and had booked a hotel at the airport. On one of the occasions my friend was drunk and on the way to his, I told her I didn't think she was sober enough to get the train I tried to stop her. Long story short she ended up at the wrong station with a dead phone and when I called the bf to ask if she had arrived. He told me she's at the wrong station obviously with another guy cheating on her. I panicked asked what station and went to find her she was fine in the end. He spent all night calling me calling her a slag said I was cheating on my partner I was a whore she was a fat slag it went on and on. Had to turn my phone off. My partner kept telling him I wasnt cheating on him and that she was safe with no guys and not cheating on him and please calm down he accused my friend on sleeping with my partner. She won't leave him but that's her Decision I give my support to her no matter what happens. But speaking to family today I've done the wrong thing in declining an invite for drinks with them both. I see her atleast once a week but family are saying I should accept the boyfriend and not seeing her with him means where alienating her
