Nakakapagod intidihin yung friend ko

Problem/Goal: How do I wake tf out of my friend.

I have a gay friend na naging close ko because of our experiences and also kase same kami ng goals sa life. Currently in a relationship sya with someone right now for almost 2 years.

Context: My friend is the one who pursue him, from the start. Yes, very very supported ako sa kanya because he told me that he’s never been happy like this before so I gave it to him. Pero to find out na this guy he’s trying to pursue is already microcheating on him even they promised to be committed to eo. So I had bad blood with this person when I found out about it pero yung friend ko keep on telling me na it’s okay lang and they’ll eventually fix it. So ligawan stage lasted for 5 months until sinagot na sya ni guy. My friend would always, ALWAYS take care of him pero this person can’t seem to let go of his micro cheating habit hanggang sa nag last sila ng 1 year. When they celebrated their first anniversary my friend found out na this guy has been posting explicit contents here in reddit as well as trying to bait users about meeting him etc. Of course, my friend na mahal na mahal kuno sya forgave him. However, their 2nd anniversary he discovered a unforgivable thing that this guy did. HE HAD SEX WITH SOMEONE 1.5 years into the relationship ang masama pa is sinisiraan nya pa to dito kay guy and their connection is on and off until they celebrated their 2nd year anniversary just recently.

Nahuli na ng friend ko but no remorse to this guy didn’t even say sorry agad or umamin nalang kase nahuli na sya.

Steps Taken: My friend cried a lot and even his mental health is affected. I talked to him about na i let go nya na pero gusto nya daw ubusin sarili nya before letting go.

This guy did a lot of things na I wanted to list here but bottomline: This guy is a fucking serial cheater.

Idk what to do with my friend rn. Also, they will celeb their monthsarry this sat. Happy monthsarry to them I guess lol.

Anyone had experience this with their friend? What did you do to slap them out to reality?
