Had an argument with my partner last night where I ended up saying that I don't want to be with him anymore because of how I now feel he thinks of me.
Someone who i was a friends with benefits type person before i met my partner, liked my profile picture on Facebook a couple months back, my partner must have been on my Facebook page and saw this and just went off on one last night. Started off as 'why is he liking your picture' , 'there must be something going on then', 'he's messaged you then obviously to just be liking your stuff', 'block him now'.
I've said I've not spoken to him / he's not messaged me , you're having a go at me over something that I haven't done, and said I'm going to bed because I don't need someone talking to me like he was when I didn't think it was a big deal at all, it's just a photo.
5 mins later he comes in, turning the light on , so I get cross because the baby is in her cot and he's having a go and turning that on, says he liked another profile picture of mine from November 2020! So "there must be something going on" , "I knew something wasn't right when you've been doing yourself up" , questioning why I hid this from him (when I haven't it's literally been on my profile, just didn't ever think it was something I needed to bring up) and then demands me to hand over my phone which I do mainly just to prove a point that I've done sod all. We don't go through each others phones normally.
So at this point I've lost my shit and have told him to f off and leave the home (my rented place) and that I don't want to be with someone who thinks of me that way.
He didn't leave as he said he would sort something out in the morning, we haven't actually spoken yet. And after me having a go back and then getting upset after finding out that's what he feels / how he thinks of me, he says he's sorry and that he does trust me and he handled that wrong.
Our relationship has been amazing, we don't ever argue we have disagreements but we talk them out but this has wound me up so much when I haven't even spoken to the other person since beginning of 2020. And me "doing myself up" is because I've put fake tan on recently and I've lost about 5kg recently so I'm feeling a million times better in my self, eating better, I'm alot happier, and we actually have our sex life back after having my youngest.
But honestly this has pissed me off so much to find out that's how he's actually been feeling, and that he clearly doesn't trust me. Especially when I haven't done a thing wrong! And I'm gutted because I thought we have been on the same wave length in terms of that I wouldn't ever think that about him and haven't had reason too, we get along so so we'll but this has just really thrown me off.
Tbh I think i just want some advice on where I go from here. I was an an abusive relationship before him with my older twos dad and I'm not putting myself through crap again when I've come out so much stronger.
For some background, he has an ex who cheated on him with his best friend, so I understand that he will have his own insecurities, but I've given him no reasons to not trust me.
Who is unreasonable, are we both? / am I unreasonable for ending things / just any advice please
