<human>: Can you condense the text into a few key points?

I've knows my girlfriend since University and we've been dating ever since, I was supposed to propose this month. I have to postpone that because my mother passed away last month, my father passed away to blood cancer a few years back, and my mother to an aneurysm a month ago.

This happened the same month but I haven't been in the best mindset to deal with it so I've put it off until now. 

My mother passed away on the 6th last month. She lives in the UK so I went to be with my family and support them and myself for a while. My girlfriend didn't come along as it was a last minute flight and she had just flown out to Vancouver for business.

I was with my family, essentially just my 2 brothers and some cousins, for 2 weeks, I came back to get some belongings so I can relocate there for a month or so. My girlfriend knew I was coming back and was going to come with me.

I came back on the 21st but was supposed to come back a day after. I took a taxi home as my girlfriend was still, according to her, in Vancouver. There wasn't any car in my driveway or shoes on my porch, I wasn't expecting anyone to be home anyways. I came home around 1am and walked straight into our bedroom and she was sleeping there with some other guy. 

I didn't wake her up or anything and I've been at a hotel every since. She's been calling me for weeks but I can't answer. I really don't know what to do, my family wasn't very close but my parents meant everything to me. Seeing my girlfriend there made me realize I don't have anyone right now..

I'm sorry if this is really jumbled but it's 4 am here and I'm drunk and crying and trying to collect myself. I really appreciate any advice you guys can give me.
<bot>: Flew out to my mother's funeral, came back to my girlfriend cheering, haven't talked to her or been home since.
