Hello there and welcome to PC!
Learning to keep relationships is hard. I have many relationships with people, maintaining them is another thing. That's where my issue lies. I disappear quite often from people.
I have been in relationships, but I am at the opposite of the spectrum, I just love way too much and get too attached.
A therapist is a great idea. I have had mine for close to 7 years now, and the point of having him there is not to "fix" me, because the only person that could do the fixing is yourself. He just guides me in the right direction and advises me on what I should do. But its up to me if I want to follow it, its just nice to have someone to talk to every couple of weeks, that knows me inside and out and can offer a non-judgmental point of view.
Good luck and at least you found this site, its a great place to help you through things.
