Re: Ex has a new BF 3 weeks later?
I agree, stay away from her profile. She's using facebook as a weapon. Take comfort in knowing that she is insecure for doing that and that your going no contact on her is affecting her enough to use the "in a relationship" status to rile you up.
Even if she is with another guy don't worry about her jumping into a relationship that fast. If I were him I'd be like "wtf, we're in a relationship already?!!". Relationships that start that fast after a break-up are destined for failure anyways.
Just do your thing and focus on healing and moving on with your life without having to use another person like she is. When you're ready you'll be able to start an amazing, healthy relationship with another person--unlike your ex who can't be alone for 5 minutes. The best revenge is happiness.
