I can’t do the boyfriend girlfriend one since I’m single, but here’s the other ones. ((I can’t see the original question on my iPad so I’m going to try and remember all the ones you asked for.

Dear ex-girlfriend,

We don’t talk much anymore. We were together for two months, and shared a mutual breakup. I hope things are going well for you; life’s complicated right now for me, but that’s irrelevant. It’s a shame things didn’t work out, but it was for the better that we broke up.

From,
Jack

Dear best friend,

I’ll try not to get too mushy in here; you know how I feel about you, so I’ll just give the sparknotes version. You’re the platonic love of my life, a soulmate like no other. You’re both an anchor and a balloon, keeping me grounded in reality while helping me just float away from my cares when I’m down. You’re the encourager and cheerleader that gives me a reason to get out of bed. You’re patient and forgiving when I least deserve it, and more loyal than one would find possible. You’re truly amazing, and your existence has been my life ring, saving me from unspeakable consequences.

Love,
Jack

Dear ex best friend,

I haven’t talked to you in years. We just kind of grew apart. We went to different schools, our interest became different as night from day. You found new and better friends, and all of a sudden I never saw you anymore. I hope your life is going well, I may never see you again but we had a good few years together.

From,
Jack

Dear future me,

Don’t fuck up, seriously.

From,
Jack
