I think it took me about 5 months NC to start a new relationship, but that didn't work out. I was much happier but I still felt that I had some issues I had not dealt with.
Now, it's been 2 years NC and in that time I have become a much more independent, happy person. Now I feel ready to start dating again, but because I am so comfortable being on my own, I don't think I'll have any trouble saying goodbye to a relationship with red flags.
Don't worry Pinoypride, things will get better! Just keep working on yourself
