<human>: Can you summarize the given text in a few sentences?

It's been 5 months and all of a sudden I've found myself admitting that I do miss her. eurgh! We weren't really good for each other, we connected on certain things especially on a physical level (sex). She had really bad insecurities, which led to her doing a lot of stupid things that I even tried to help her through, but it just didn't work.

Since I was 16 I've been in three 2 year relationships and and one-1 year relationship, each right after the other. I realised this is a lot, and that I depend on the female company too much. So over the last 5 months I've focused on friends, new hobbies and planning a holiday. I've hung out with a few girls but honestly with all the bad stuff, me and my ex had certain connections I don't think I'll find in anyone else. She really could have been the one guys. It's sad. How long does this last?
<bot>: After 5 months I realise how much I miss my ex, but she's not good for me. I've tried to distract myself but nothing is working. I miss her :(
