<human>: Can you summarize the given text in a few sentences?

So reddit I have a problem. I am madly in love with my best friend of 10 years but the story doesn't start there. It really started about a year ago when he confessed his love for me. I completely pushed him away because I was at a rough time in my life. I had just gotten dumped, lost my sister in a car accident and my job. I pretty much told him to go away and that I didn't care how he felt. After some therapy I noticed he was always there for me when I lost my grandparents, every birthday. My first job everything. Well I decided I needed to apologize to him and that i want to start a relationship with him and see if he would take me.. It's been a year since I've bad any contact with him so I looked him up on social media. Well it turns out he has a girlfriend. I messaged him and asked how he was and how he's been. He told me about his girlfriend immediately after we started talking but it just seems like he isn't the same guy I knew a year ago. In this year he's done so much and changed. I wanted to speak to him in person maybe go for coffee or something but he basically straight up said said no. I've been pretty much stalking him on social media and I just can't stand seeing him with this girl. She doesn't work. Stays at home all day unless they go out together from what I've seen and heard from others. I asked our friends and they've pretty much said they rarely see him. I want to do something about it but he seems happy. I miss him so much reddit but it seems he doesn't want me in his life anymore. What do I do?
<bot>: blew off my bff when he confessed his love to me got better now I want him back but I may be too late.
