Need advice

OK so here it goes, I've kept everything bottled up inside for awhile now. So here's the thing I want to talk about and get advice on ASAP because I don't know what to do anymore or who to go to.. everyone I knew doesn't talk to me anymore and that includes family. So I've been in a relationship for almost 3 years(longest relationship I've been in), I don't know how to explain this that much but all I know is it feels like it's falling apart. I've had this fear of being alone when this relationship does end, I don't know if I'll be able to handle it. I just need advice on how to cope after being in a long relationship with someone you fell in love with????

Firstly if u love each other then dun go for break up.Character and integrity goes hand in hand. If break up is ur final decision then i ll say that time is the best healer.Take admission in a university make new frds (both genders) and enjoy life.Cycle of replacement is the biggest truth of life.

Surely if fear of being friend and family-less is what's stopping you from ending this relationship like you'd like to, the solution is obvious? WHY does everyone you used to know no longer talk to you?
