You gave them odds to set mine, and it seems you payed their set mining strategy.
MP1 has also a full stack (around 96BBs), so the flat cold call on the flop is even scarier than a re-raise, as you can still re-pop it on the flop after a good sized lead on the flop.
So, after Button re-raises you huge, and MP1 flat calls, I agree your are probably beat here and drawing very thin, I would say more than 80% of the time at least.
When you do not have any read, at least take the time when you are facing this decision to check the hand history for the hands these players won.
If they didn't get out of line, the fold will be easier, and if they were pushing any two you can call confident.
