Interesting..interesting indeed..so you heard this over a cell phone convo...a snafu'ed 3 way call...Hmmmmm..interesting..anyway..I can see where it might be posturing or male BS as it was referred too.. I also see no harm in keeping an eye out for a bit given your H's history..
trust but verify
I can also see it from the other side..men talk about their conquests all the time with each other..men also talk about their feelings ladies..some of us anyway..I've got a buddy..hard core playa..never been married..fell for a girl..got crushed..playa cried on my shoulder for weeks..so we do discuss our feelings..
