Aye it's pretty common. It's also extremely common to lose "friends" over the years, especially after finishing school, college, Uni, etc. But it doesn't mean you can't find new acquaintances and potentially turn them into friends.
I'd also like to comment that please don't feel obliged to go out drinking to maintain "relationship" with others. This is no friendship, people simply get drunk together. Once you take away the alcohol element from their "relationship" the whole "bond" breaks up instantly. So please don't feel you need to do that.
Things that can help develop bonds with others:
- Find like-minded offline groups, communities, clubs that align with your interests. this could be sports teams (I found them to be the best to build good and genuine bonds, but each to their own), hobby groups, books clubs, etc., etc. I remember at Uni we have so many clubs I had hard time deciding which one to go.
I've been a part of a cinema club, bouldering club, there was a D&D one too which I regret to this day I never managed to find time to join.
- Quality over quantity. Rather than having lots of superficial friends, I'd definitely choose to have 1 genuine friend over 100 so called "friends"
- Be genuine. I like this quote from Jordan Peterson: "If you don't manifest yourself int he way you are, then there is no way that a path that's proper for you will reveal itself".
- Practice active listening and show genuine interest in others when talking to them. People appreciate being heard and valued. This one is such a rare thing that just being a great listener (giving the person time to talk about what they are passionate about, asking the right questions, genuinely being interested in what's going on in their lives) will make the others want to see you more often in their lives. Ask me something I'm passionate about and see me moving all my priorities out just to meet you and have a chat again.
- Plan things yourself. Don't wait for others to reach out and invite you over for XYZ. Take the initiative.
- Stay positive and patient. It takes a lot of time to build an actual strong bond, years sometimes, so accept to take it slow.
All the best
