People do fundamentally change sometimes, but mostly they just get older LOL.

It's probably best to not engage at all.

I'm sorry you went thru the experience, must have been very hard on you.

Just my opinion but seems like a selfish move on his part to contact on V-Day of all days!! Seems impulsive and if he is doing great, well-situated, etc, he would reach out last week, last month, next week, next month versus Valentines' day.

Which may be indicative of the actions you should take, which is probably zero.

Hang in there.
