We would be perfect together.

Your abject disdain matches my debonair insouciance.

Walking with friends is the perfect foil to my cya later off you go encouragement.

Surround yourself with people that have similar interests.

Hit on talent when the mood takes you.

One of those fuckers might be just right.

Get lucky.

Too bad about your dog & cat issues. Because if you could take in the animals, somebody else could adopt the human

Somewhere there's a love just for him.
I don't believe it's you.

Your instincts are right on as usual.

Run in the opposite direction of this guy.

Um, I think you already know what to do here. Better luck next time, yeah?

I am with you don't go there under any circumstances. Stay single and keep on hiking.

Always follow your gut instinct.

He is more interested in himself than in you. I commend to you each of the comments below.

Sounds like he's on the rebound, before he is divorced.

He could be 'the one', but how are his attachments dragging him down/holding him to ransom?
I recently met a lady in need of a smart brain with the ability to be non-judgemental. I had a not so soft spot for her, but her life baggage is something I cannot cope with at this time. If we'd met some time ago then fine I could help providing I knew then what I know now.
So, to cut to the chase, you may find that you could become attached then discover than you end up fighting what feels like Vietnam but with emotions instead of bombs and bullets.
He has a point on your smile though, a very good point.

Years past, I had met several similarly desperate-to-not-be-alone men, and actually took up with one charmer who conveniently forgot to mention his last, not yet divorced, marriage. Ugh. Our generation raised men to be cared for by women in order to succeed. They tend to be terrified of the prospect of fending for themselves, my ex included.
Nah, you have FAR better things to do with your life than being his next hand-maiden!!

Ohhh, he sounds so loveable. Wouldn't you just love to rescue him from that trailer and take him and his pets home and then provide for him and care and nurse him for the rest of his life? What instinct other than self preservation do you need here?

Trust your instincts

Run away!

That's enough red flags to tell him to look else where.

I think that you have listed enough reasons to forget him.
