A big, warm hug to the questioner from afar!
Let's dive into the questioner's description:
He's not one to turn down an invitation! He's got a great same-sex friend, they eat and walk together, and they chat with the opposite sex now and again. He's a very sociable guy!
I just started university and met several people of the opposite sex who were really friendly and took the initiative to chat, ask me out to dinner, hang out, and study with me. We weren't close, but just like in high school, I gradually lost contact with everyone except him.
He often told you he loved you, confided in a classmate of the opposite sex, talked about life goals, hobbies, and life in general, had a good time, and added each other on social media with private accounts. But then he felt scared when things got a bit out of hand.
It can be tough to reconnect with friends when everyone seems to have a new circle. It's natural to crave the company of friends when we're feeling lonely. Having a good support system of friends to socialize with is so important.
A few words for the questioner:
It seems that the problem the questioner is facing is not really an interpersonal problem, but is caused by the views of some people. And the questioner is a nostalgic person who really hopes that the friendship will last forever.
And then there's some independent thinking about the sense of boundaries between people, which is a great thing! It shows that the questioner is also reflecting on himself and thinking within a normal range.
On the one hand, the questioner is just too nice to argue and just explains his actions, which shows his easygoing personality.
The OP has already begun to experience that, in fact, the emotions between friends will fade, and sometimes we will re-establish new relationships and build new emotions. It can be tricky to meet old friends from more than ten years ago! This is also the norm in life.
It's totally normal to feel a little lonely sometimes. The good news is that if you give it time, you'll get used to it. And before you know it, everyone will love your way of doing things! It'll be so much easier to build long-lasting relationships.
Some people just naturally drift apart, not because the relationship has faded, but because everyone naturally gravitates towards the feeling that is more comfortable in the moment.


Comments
I can totally relate to feeling lost when it comes to setting boundaries. It's tough when someone you care about misinterprets your friendships. I wish I had known better how to handle those situations back then.
It sounds like you were just being friendly and open, which is a great quality. But sometimes people get jealous or insecure. Maybe next time, you could try to be a bit more upfront with your partner about your boundaries from the start.
That must have been really hard to go through. It's important to find friends who understand and support you for who you are. Perhaps joining clubs or groups that align with your interests could help you meet likeminded people.
I admire your honesty in trying to maintain those friendships. Sometimes, relationships evolve, and it's not always our fault. Focusing on selfgrowth and doing what makes you happy, like reading, is also a valuable way to spend your time.
It's sad that things ended up this way with your ex. But remember, you're not alone. There are plenty of people out there who would appreciate you for the person you are. Maybe reaching out to old friends or making new ones online could be a good start.
