I'm A Bi Boy How To Rekindle My Old Relationship With My Friend?

If I were you I would send him a msg saying "I really miss you" and if he says same then tell him "remember when u held my hand that one time" use your own wording as Im sure you would know what really happened and If he says: "Yea" then say "I loved that and wish we could do that again, and playing footsie" Thats something along the lines that I would do/say, and if he did not want to go on with the convo then I would know to let it go. I know that jealous feeling from him having that GF. Need a buddy to talk to or a 2nd opinion Im here. Hope this helped you in some way or give you and Idea and you two become friends again =)
