Choose my happiness or my children

My late husband passed 5 yrs ago. I finallymet a man that makes me happy. I've been with him 4 the last 2 yrs. On.and off. I moved away to give us space and time apart because my children teenagers don't like him.. mind u i move to Tx after their dad passed becausei just could not be in.thst house without my husband. So my children 18, 16, and 15 wanted to move back to fl after a year of me being with this man. They literally gave me hell. So we moved away. This last year me and this man have slayed incontact and have talked about how much we love each other. He wants to come to live with me but at the same time has small children. He doesn't want to leave behind. Which i completely get. But he wants me to leave my teens with.their older sister. And move back to tx. I told him that it was best we both stay with our children. And maybe later on God willing we could try again. He isn't happy about but i am so sad. I love him so much but not enough to keave my kids. When is it my turn to be happy? My18 yr oldwants to move out my 16 and 15 yr old don'twant to live with me if i choose him I'm heartbroken. Need advise plz...p.s i have a 27 yr old want to go live with if I choose.this man. I'm pretty sure what I'm going to do. Just want some others opinions.
