@Scottish no honestly i've just struggled with some toxic relationships before so my mindset is completely jumbled. I always feel as if things are my fault, not going into it but i have a bunch of other issues that are all thrown into this that make it worse.
I semi addressed the insecurity issue and he sent me a message back explaining his feelings for me and trying to reassure me. I've written a long message about the instagram thing, the disrespectfulness and other things. Will send it in the morning now because he's gone to sleep and i'll have a bit of a clearer head by then.
I really do just struggle with relationships, not even just romantically because of mental health, trust issues etc. So honestly hearing all of your opinions and kind guiding words has helped so so much
