What does this mean?- the WH's regrets?

[newmama]

It is very confusing, Gatsby! I can't help but wonder if your WH is just afraid that having a family means his "life" is over.

He wants to go live and work in Ethiopia, he wants his space, he is crazy about you still.....ahhhhh!!

In fact, this drove me nuts when my stbxh was acting all weird before I knew he was with OW. WHen I found that out, it was like "Ah HA! THAT explains it!" But I can't say that I think your WH is with an OW! Honestly....not enough red flags...
