Well you meet one person with aspergers you met one person with aspergers - it's unwise to generalise, I'm shocked a therapist did just that.

My cousin has aspergers and is happily married with a child. Yes it took him a while to find the right person, he got hurt quite a few times along the way (he is very trusting and often has been taken advantage of). He is however a loving, hardworking and loyal husband and father - he can be very focussed and he has focussed on being those things and does them well.

You sound like you are also trusting and that has been abused by others. Do you have friends or family who can be your wingman? Help you assess situations, give you feedback?

I do recommend finding things you love, like Erebos suggested - follow your bliss, you may well find you meet someone special along the way.
