I would commend the OP for noticing future issues even before committing into this second marriage. A lot of divorced women feel so emotional insecure that they jump to marry the next person and ignore all the red flags. A lot of ladies her have rightly pointed out that the first wife doesn’t seem to be a priority when he was married. Mommas boys will never be able to make u a priority no matter what. In my personal experience, they never change. That is another reason why he is so laid back at texting. The future partner should be his interest and passion and priority and the OP is clearly not this guys priority. He might be talking to a lot of other girls or he might not be interested to woo the OP. Bad future husband in my opinion. The OP should think about taking chances with her second marriage. Atleast the guy should show keen interest in communicating to her whenever wherever clearly missing in this case.. just my 2 cents. Kudos to the OP for bringing up the red flags!
