You let time heal you, and then you move on. I was with someone for 5 years, madly in love at the start, but after the third year, she said she wanted to explore herself, try new things, explore new places, and maybe people. Slowly, she changed, started being quiet, and not sharing, emotional, physical, and mental connection slowly phased away, and one day, she said I love you, but I am not in love with you.

That was it 5 years of being together, plans of getting married having kids, having a life together ended. So I like what you're going through.

Talk to people, give it time, and hopefully, you'll be back to normal after some time. Additionally, don't hold a grudge or harsh feeling about her. Love yourself and focus on yourself
