Hard partner

I think my relationship has come to an end, I’m really past over it.

My partner is really hard sometimes and I just can’t deal with my emotionally and physically anymore!

Yesterday we went to the Boxing Day sales to the shop and my brother msged and asked us both to come for a drink at his friends later which my partner agreed too, and was totally fine with. I know she has bad anxiety so I asked multiple times if she’s sure! And she said yes, so I told my brother yes we will come after shopping.

We were going to go all the way home after the shop and then get a taxi back ( it was 5 min from the shop the friends house was) but we wanted to have more then a drink. But after shopping for 3 hours my back was sore and I was exhausted so I said to my partner we will just go straight to his friends for a drink and I’ll just drive then we can leave after a drink… we’ll because I changed the plan she flipped …. How she doesn’t wanna go now cause she needs time to process new plans and what a fucking joke apparently and argued with me about it.

I never ever see my brother much, and he both asked us to come.. in the end we went for one drink and left to go home.. and then it all started .. I went toilet at home and she went for a walk and she starts msging me while in the same house then me saying how much I hurt her, and I clearly don’t care about her feelings and I’m selfish…. Because I changed the plan, and she didn’t have time to process the new plan.. and it went on and on and on till 1am…

It’s always like this … she wont talk to me in person but she will happily msg me and argue with me and just blame me about everything .. it’s gotten to the point where I just don’t care anymore .. I did nothing wrong …

She was like sorry.. I said what are you sorry for and she goes “ Putting my feeling second initially to try to make you happy”

I just feel like I can’t do it anymore .. things always get blown out of proportion and I try ask her to talk to me in person but she says “ I’m not interested in talking to you” but will bloody msg me.

I need help…‘I’m starting to be unhappy again.

I was in an abusive relationship for 9 years and it was very hard to get out of .. I was finally happy with life and my daughter then I met my now partner and it’s just hard work.

Anyone have any advice for me?
