Confused

Well let me start off by saying I'm 30 yrs old and im in an 3 year relationship with an 57 yr old man. And I'm a mother of 2 but not his. Well I been through alot with him from him cheating on me with disgusting ppl to blaming misscarages on me. To make a long story short one day I went to his house and some handsome guy was there and my boyfriend introduced us and as soon as I looked in the other man eyes it's like something came over me. So later that night my boyfriend went in the house and I still stayed outside and listen to the other man conversations and stories from back home. So somehow he got so intuned with me and we started asking questions about each other and im thinking this man is exactly what I want. He's 43 btw. So before he left he confessed his love for me and I'm not going to lie I think about him too. And have feelings for him. He's coming back in another month and hes been calling me since he's left. I have caught feelings for him deeply myself. I want to leave my relationship I'm in now for him. But what you all think
