TITLE: [18 M] I'm worried about a type of personal problem I have with dating
POST: I'm not new to relationships, I've had quite a few. And I've liked them a lot. I've even been in love with a girl or so before. But there is an issue.

My first few highschool relationships were definitely bad. I was played, screwed over, lots of simple stupid bad stuff. Later on I noticed that in a couple of my relationships, I had a weird thing happen. Such as mid way through a relationship I just go blank. I lose all feeling for that person. I like them. I KNOW I do. But it's very confusing.

It would ultimately end up ruining the relationship because I had no idea what I felt, or thought at all. 

Then there's these other times, 

Where I've found a girl, and slowly over time, I would absolutely *lose my mind* thinking about this girl. It was almost like a full on love. 

I believe I do love everyone, and that may be what I feel. But It gets to the point where I will panic and stress out hard at the most simple things. Id look into every. single. Detail. And think it was something bad. And worry. 

Right now, I'm curious.

I haven't had a relationship in 6 months. Last one was a relationship similar to the latter I described. I'm horrible at dealing with either. Would anyone have any advice on what exactly would cause me to 

-Lose all emotion or feeling to a person

Or 

-Gain a crazy amount of attraction and emotion to a girl.
TL;DR: 
Halfway into a relationship I'll lose all feelings I have for a person. No matter how strong. It worried me It may happen again or I may not experience a real, meaningful long lasting relationship.
