Sounds like persuing either of those past friendships wiukdnhave a lot of drama involved & not good to get further involved with. Sounds like friend 1 has already decided not to continue wirh persuing a friendship with yiu for whatever reason by just not responding to you.

I would just hang back & see if either past acquaintance contacts yiu & persues the a friendship farther.

Sometimes I have met up with people from past experiences together....reminicing was all it amounted to because we no longer had much in common & neither continued to stay in contact
