You know those friends that you meet and think I can see you being in my life forever and then after a few years you lose contact. Well, that’s what happened to me after I graduated from university. I met A and H in my first week of university and we hit it off right away we all studied the same subject and lived next to each other. We also lived together in our second and third year. But over the years they both got boyfriends. I lived with them and studied the same subject and saw them once a week. When we met up it always felt like they did not want to be there and would rather hang out with their boyfriends and I’m not going to lie that hurt my feelings.
When we all moved out from our third-year house we promised to stay in contact. I had little to no hope of that happing and I was right. The first sign of us not staying friends was them not coming to my party. I understand if I told them a week before, but they knew about this for about three months and even agreed to come. A few days before I sent out a message to them to make sure they were still coming. But I got the response of “I forgot to book time off work” and “I forgot it was my anniversary with my boyfriend” The second sign was when I tried to keep in contact with them but got blanked or ignored on the group chat.
This is one of those things they don’t really tell you about adulthood; that losing friends is much more common than you would like to think.
I've lost a bunch of friends over the years during university as well as after - I think it's really sad but also an unfortunate part of life, and isn't talked about enough as you said. I am often wondering if it's a problem with me but find it unhelpful in terms of maintaining a positive outlook on things. I hope you get to meet or re-connect with some great people soon :)
