is it possible to lead a normal life with no friends?

[tough nut to hack]

i cant define "normal" nobody can, each of us have our own way of doing things. but like everybody else i go to work pay taxes rates and rent tv license ect and have a beloved other half. but i have absolutely no friends either in work or outside of it. my missus does, she goes out with her workmates past and present and has contact with mates from school 20 odd years later. for want of better words what little mates i had turned their back on me and i dont know why. i know i'm not happy with life, but i'm content with my surroundings. i havent been out on the tear for nearly 4 years, i feel stagnant i promised myself to my fiancee and i've stood by it. i just want a good piss up and some male banter. i suppose its like a scab, scratch it hard enough it will bleed again. but i'm a scab that wont need much scratching. do i sound like a man on the verge or like a complete wanker? i'm very lonely
