He has fallen out of love with me 😞

I’ve been with this guy for 4 years and he has fallen out of love with me and he is being distant. When I try to break up with him, he would beg me to stay. I have a friend who really makes me laugh and I’m kinda into him, and he is kinda into me, but I haven’t told him I have a boyfriend yet.... Recently I’ve heard rumors that he might ask me out. I really need help. Thank you for reading this and have a great day
