I Want to Be In a Healthy Loving Relationship

My boyfriend doesn't want to leave me. However I think he fell for his ex while we were having some problems and she messaged him...he can't have her as she is in another relationship with a very successful guy...apparently a lot of women look for that in a mate...let's be real. My bf is in construction. He tells me he's trying and will continue to make things work with us.
My bf ex doesnt want my him but she messaged him for a companies number...looks like she dont want him be with me so she got him wrapped around her lil finger now.
I want him to get over his ex though. The thought that they can't be together is comforting... Smh.
