I’m 28/F in a relationship w/ a married man

Problem/Goal: Should I stay and wait until na process ang annulment?

Context: I’ve been in a relationship for 3 years with 31/M he’s married w/ kids. When we met, hindi ko alam na he’s a family man. Until, I found out and he told me na nag process na siya ng annulment because of there issues. His mom and sister also talked to me about it. Should I wait until ma-process ang annulment nila? I feel like Im left behind, my friends are setting down. He’s kind, mature, thoughtful and responsible man. But lately I’m so anxious because all my friends don’t know about his situation. Natatakot ako na yung girl would post me on social media which can ruin my career
