Cheating again

Id appreciate it if I had someone, guy or girl, to talk to, maybe become close to. I have suspicions my partner is cheating, theyve done so in the past twice and each time I took them back I know im naivé but I thought they could change, I cant even coherently type because of my ADD.

I voice my concerns but nothing changes. They havent talked to me in hours and the attention they give me has dissapeared. I feel neglected ngl. That is all
