I have been dating my boyfriend for 4 months. We have had a few conversations about the future and both want this to be a serious, possibly permanent, relationship. The other day the possibility of moving in together in a few months came up.

He is very loving and affectionate. We spend a lot of time together. Everything is going well.

But I am still irrationally insecure. The more invested I get in the relationship, the more afraid I am that it will just end out of the blue.

What is wrong with me and how can I fix it?
