The LDR I was in is still one of the relationships I am in now. I am just stating that LDRs are incredibly difficult, at least for people like me that love affection. We didn't really have many issues besides the lack of missing each others touch and presence.
If an LDR is all someone can have at that point in time, it's certainly a lot better than nothing. I feel it's like this.
5) No relationship
1) physical relationship
Hence if you're at #1 and it returns to #3 you're regressing in my mind, but still, it's better than nothing.
