I brought a titanium black matte engagement ring... It's not for me to propose but I do want him to know I want him forever . He can also use it as his wedding ring . But to rethink my let post, he does want to propose to me with the ring I picked out a year ago.. I'm sure he's still paying it off... Maybe that's why he wants to wait... Idk ... I wish he would just keep that part to himself and stop mentioning the marriage thing because it has me confused.
