<human>: Can you give me a shortened version of the text?

I've got a girlfriend for a couple of months now. I'm very happy and I believe she is the one. Before my current relationship I was in a relationship for about 6 years.

My current situation is as follows. We see each other almost every day. We call every day and miss each other like crazy when we are a part. I met her parents, she met mine, we're going on vacation together in a couple of weeks. I met most of her friends, the same for her with my friends.

If I look at our relationship from a pure logical point of view everything is good. There is absolutely no reason why I should feel afraid or not happy but some reason I can't shake the feeling.

The problem I'm facing is my fear of loss. When she's away I constantly think, what is she doing, is she texting other guys. Does she like them. I'm scared she calls me up at one point to tell me it's over.

It's even come to a point where I'm seriously questioning if I should look into her phone to check, even though she hasn't given me any reason not to trust her.

I've thought very hard about this and came to a few possible reasons why I am this way.

* My ex-girlfriend left me after 6 years, didn't see it coming. I thought she would never leave me after such a long time together.

* My Girlfriend is very open about sex (which is a good thing) but sometime I get the feeling she doesn't see sex as such a special thing (which I do). Which is my minds translates to: "If she doesn't think it's special she easily has sex with other people"
<bot>: I'm really scared if I continue this behaviour of insecurity and not trusting. I might destroy the relationship and lose "the one".
