Yes get back to your husband and make the marriage work, if you have lost four stone you must have been, quite a hefty size (what are the stretch marks like?),I can't imagine what type of man would want a clapped out fifty plus model, when there are much younger and better looking models available,
When reading the description of your life style, cloud cuckoo land springs to mind,if you are really serious about dating again try ringing age concern!!
