Complicated

I’ve always had a very complicated love life. I’m pretty sure it’s a curse since my family also has also had very poor luck in love. I’m with my partner from before and we’ll a new one. I’m poly. My original partner absolutely hates my new partner since my new partner has cheated on me before. And don’t get me wrong I broke up with said partner and gave him living hell for a while but I’m giving him a chance. My partner hates it and what he did and I don’t blame them but also I gave them chance after chance with serious addiction problems and when he wouldn’t talk to me for months because he’d do shit and go to jail or rehab and I stayed through it all with him and gave him chance after chance but he can’t stand I’m doing it for someone else. I’ve told him that this is my choice and if  shit goes bad it’s completely on me and he needs to trust me and my decisions. Because it worked out with him maybe just maybe it’ll work out with this other person
