so through the last year i’ve had a couple relationships, came out of one and went straight into another (i had no feelings left for the first one and it was just a toxic relationship and difficult to leave, i’m over him) and ive started to notice in both of them i have a habit of going from absolutely loving them and revolving my world around them to not liking them, not wanting to see them, talk to them, ect. with my ex this was absolutely massive, happened very fast and very often, and it played a huge part in me confusing my feelings for him. with my current partner, its not as quick or frequent but ive noticed that at first, i was practically in love with him, wanted to do everything with him but for the last week it’s completely switched up and i never feel like seeing him anymore. it’s been really worrying me because im worried that the love and enjoyment might not come back, like how it didnt with my ex. of course i care about my partner and the last thing i want is to hurt him, especially without valid reason. i have no idea why this happened, and im certain that i must still have feelings for him. is this just me making an absolute mess out of my feelings? or could it be my shit show mental state again 
(btw before anyone comments it, i’m aware of how unfair this is to my partner, hence why im trying to figure it out and put all my effort into letting it affect him in the least way possible)
