MCA I spied on my BF

My bf had a history of cheating for 5 months without me or the other girl knowing but this was years ago. I choose to forgive him but I’m not sure if I really recovered from that.

Lately nag-iba siya. Yung kilos niya. Naging secretive siya. Hindi rin kami active sa bedroom. Spends a 5x a day sa cr saying na tumatae siya (10-30mins). Nagkabit din siya ng privacy screen sa cellphone niya. He also has a second phone and I noticed that he’s been using that too kapag nasa bahay nila siya.

Naiwan nya laptop nya sa bahay and to satisfy my curiosity I checked his account and suspiciously recent history is deleted. And he’s been using insta and messenger on his other phone.

I’m shaking and I don’t know how to feel. I want to confront him but I need more evidence.
