Oh I am sorry you developed feelings for someone and ended up being let down like that. All relationships we try to engage in are a risk, we can learn a lot of hard life lessons when it comes to experiencing different relationships with others. Ofcourse you feel broken hearted, you were genuinely interested in seeing if you could actually develop a relationship with this person. Your hopes got dashed and that always hurts and/or is deeply disappointing. Yet, this person is recently divorced and may not be good "relationship" material for someone like you. You sound like a nice person and perhaps this woman is more attracted to men not as nice as you. That is not YOUR failing either, in all honesty some people tend to date a certain type and may even end up experiencing several failed relationships because of that.

Learn from this, notice the red flags that were there before you got to this point where you were just dropped for someone else. Also, be thankful you did not invest more into a relationship only to be dumped further down the road in the relationship. Also, it's best not to get involved with someone right after they break a relationship with another person, especially a marriage. Often the individual is too interested in repairing their broken self esteem and they are not really ready to see you and appreciate you for who you are.
