Thank you very much everyone for all your answers, I mean, woww!! There are so many!

Re-reading quickly my initial post, I wasn't sure if you people would understand my situation because quite frankly, it wasn't so clear in my head ...but I'm glad you did.
Looking at all your wonderful replies, many things come to my attention. First, I feel guilty for being single but I should not be. My father, her gf, friends, my mother, my family at family meetings, they're always all asking me if I made a girlfriend and I get y'all, it's so badly seen to be single in today's society. Actually, were there a time it was NOT the case? lol In the 40s to the beginning of the 60s, in my province, people were extremely catholic and it was a sin for a woman to not have kids. Or for a man to not have a woman. I'm not catholic but all that to say, I think it was never well seen to be single. Then again, this is MY life and like Daria said in episode 65 of Daria, ''it's my life, it's my choice''. For some reason I cried when she said that. LOLL
Second, I'm still young and shouldn't worry about being single forever ...not until I'm 52, at least. Hahahaha! I mentionned I'm an intellectual, I think about a lot of things and I often wonder these existential questions. Will I regret not having kids? Will I miss the love of my life by staying single? Will I this, will I that? I now realise I try to predict the future TOO MUCH and since the future cannot truly be predicted, I'm worrying for nothing.
Third, it would be a mistake to force myself onto a relationship right now. At the light of your posts, I am CLEARLY not ready for a good, FURFILLING, stable, relationship. Also, I'm about to get my teeth repaired, I will have tons of debts to repay, I will have to work A LOT to repay them and after that, I'll be studying computer engineering for 3-5 years so not the best time for a relationship... I wouldn't say no to the right girl and I sure could use the support, I'm a very nice guy, I always took great care of my (few) girlfriends and I'm sure we'd have fun but I simply won't have much time and I don't want to waste anybody's time...
Oh well, I believe I'll stay single for the next 4-6 years, get my teeth repaired (got injured playing hockey, lost a tooth right in the front so I don't smile so much anymore, 6 need to be extracted, it's going to cost me a fortune in implants but it hurts like hell, I've got to do it, no other choice), finish my studies and then, if I'm ready, I'll see if a girl can make me be in love again...
Thanks everyone, it's very appreciated and I wish you all the best. Take care!
