Hey there, it is very hard to trust after being betrayed by someone you loved. However its great to see that you are willing to get out there and meet new people.
The guy that you have recently met sounds to me like he has a lot of issues, and in my opinion the issues you spoke about imply he would not be a safe person to invest your feelings in at this stage. I believe that when you know what you want it's easier to decide who is and who isn't good for your well being...I believe that you need to think carefully about how you feel when with this person, do you feel you can be you, do you feel you can be open and trust this person with your deepest thoughts...do you feel understood, heard and accepted?
It is your job to take care of yourself and that includes who you let into your life. So by asking yourself these kinds of questions and many more, i believe that you will be able to act in a way that best suits you.xx
