Let him take my us (me, mom and stepdad) to dinner?

we broke up 10 months ago and we still admit that we love and miss each other. to my face he's still nice but when we part, he's distance and mostly text instead of calling. frankly i feel like it's an insult as my mother thinks that he treated me like s*** toward the end of the relationship. i think that he is extremely slick and is concerned about appearing to be the "nice guy" to everyone else. trick is -- that my mom and step dad know enough and advised me to leave when we were having problems. overall, i feel like he's still not acting up to par as someone who is responsible and cares enough about me for him to sit and eat with my family, particularly elders who don't need for him to buy them a meal. I can treat them and they can pay for it for themselves. initially, i told him it may be ok and we'll talk about it but i'm leaning more toward no... like everyone else they thought he was great until he started acting like a narcissist...this time around he's dealing with people who have all info. he can play games with me but sitting and breaking bread with elders in my family who entrusted him to care for me is like crossing the line.. we went out last night and he mentioned something to the effect that we're still yzing the situation... meaning we're not totally separated. i think he's a confused soul without a clue. think he's also used to playing mind games your thoughts? appreciate it..
