Suck Less Tomorrow Than You Did Today

After reviewing my hands today I didn't lose that many. This is one of the ones that had me thinking though.

The player I'm interested in is UTG +1. Stats are 67/33 but I'd only seen him play 3 hands.

MP3 ($0.87)
CO ($2)
BTN ($0.93)
SB ($1.16)
BB ($0.90)
Pre-Flop: ($0.05, 9 players) Hero is MP2
[CO posts $0.02]
1 fold, UTG+1 calls $0.02, 1 fold, Hero raises to $0.10, 1 fold, CO calls $0.08, 1 fold, SB calls $0.09, BB calls $0.08, UTG+1 calls $0.08

Flop: ($0.50, 5 players)
SB checks, BB checks, UTG+1 bets $0.10, $0.1 to Hero ($0.87)?

UTG +1 calls my preflop raise, at this stage I'm thinking he has 44+, A8+, KJ+ QJ+. I don't think he'd call a raise with small suited cards. Against this range my equity is 46%

When the flop comes and he raises, now I'm thinking he has 99+, A9+, KJ+, QJ+. My equity against this has dropped to 22%. But I think because he is oop & raised the flop, it has to have improved his hand somehow. What I wasn't sure about was that he only bet 20% of the pot, that really threw me.

So, the correct action here is to fold?
