is this ok?

i dated a guy in high school when i was 17. he dropped out and turned into an addict. we ended up breaking up a year later. we were friends for about 10 years before we dated.

fast forward 5 years, i’m in a relationship, i now have a kid with the current guy i’m with, my life is complete. i love and trust my boyfriend.

my ex boyfriend added me on facebook and we started talking about how our lives changed and just updated eachother. we obviously have absolutely no intention of getting back together. is this weird? my boyfriend knows but he’s acting distant. trust me, there’s nothing to worry about anymore.
