My partner of 7 years keeps avoiding doing things he's promised by making excuses and recently he had promised to go to my pharmacy for my medication and kept putting it off until I finally said if he didnt do at least that then I wanted him to move back home to his parents because I do everything myself and he's always making up reasons why he can't do things and this is usually phantom illnesses that get better once the threat has passed. Anyway he promised he was going and I went out shopping and rang him about 30 minutes later to make sure he had, had no problems at the chemist getting the tablets only for him to start shouting and swearing that he had been going to go but couldn't effing go anyway now because he had a puncture on his bike he was going to ride. I immediately was suspicious because he was so aggressive and triumphant and had made no mention of a puncture prior to this and had said while I went shopping he would go to the chemist, so I said I didn't think he really had a puncture and because of many lies and mistrustful behaviours I was going to check the tyres for myself and if there was no actually punctures then I would be done with being treated like a fool. After swearing and getting angry for a good few minutes saying he did have a puncture and why the feck would he make it up and how paranoid I was I eventually said that if he admitted it then we could work through things and that if he lied I was not taking it anymore because it's not paranoia when people lie and get caught out as often as he does, he finally admitted it, but turned it into me forcing him to go while he had a sore throat and made me sound bullying and lazy and he really confessed because I said I didn't expect that he could use the bike later to go to his families and by admitting it, he could play the martyr and also not have to walk later that day. It's abuse and I know it but I feel like I'm going to never find anyone decent because my ex before him was abusive and he seemed so loving and different at first. I feel so pathetic and don't know how to stop him doing this as I'm exhausted with the lies and he's forever twisting things and making out he said things he didn't and also that he didn't say things he did. Any advice please and please be blunt as I deserve it 😢
