<human>: Can you provide a brief overview of the text?

First and obligatory throwaway since a lot of people know my main irl. Also on my phone so sorry about the formattig and grammar.

Im a 23 year old female who has had 3 relationships including my current. My first relationship i had incredibly low self esteem/self worth and didn't really ever feel the way i do about my current bf. You know that weird butterfly feeling? Yeah. With this guy (who ill call Charizard cus pokemon) i feel like i really fell in love for the first time. Ive been with him for a year and a half. I love this guy and just need advice so i can continue to make him happy and keep myself sane since we plan on moving in with each other this time next year if everything goes okay.

At the start i was confident and easy going and we never argued... Well we still never argue but i feel like im going crazy here. Every weekend i get this sense of dread on the sunday before i head home (since i visit charizard's house on the weekends since he has more space and i adore his cat). I feel like it might be an attachment issue since ive never had this feeling before and have just sort of looked up the symptoms for answers.

Ill get upset and almost feel heartbroken that i have to leave. I know i sound insane and this is an entirely new feeling for me since im usually fairly confident and easy going.

Today i was prompted to post after i had to leave and cried walking over to the train. 

I just need some advice in dealing with this sort of feeling tho even just ranting about it has made me feel 100x better. Im terrible with structure so if you need more examples or anything else just ask.
<bot>: boyfriend is calm and easy going like i used to be until i turned into this crazy feeling crybaby. Help me understand? Advice?
