Do you want the cat? You are right to focus on your life, your resposibilities, and what you need.
Most likely he is trying to figure out what he wants and is reconnecting to experience the good chemistry and relating you two have. Keep it postive, but also keep yourself emotionally safe. This is very tough to do. Our tendency is to focus so much on getting back together that not only do we smother our S with attention and demands, we bury our own hurt and leave ourselves open for more. You have experienced a lot of hurt in this process. Go slow in the relationship and trust rebuilding, continue not to pressure and be watchful.
Thanks DBintheBurg for the advice and support. As far as the cat goes, I would like to bring the cat over as long as it gets along with our 13yr old cat and MIL doesn't get sick do to her allergy to Siamese.
