Yes you can be friends with your ex if that's what you want. As far as MLC, I don't think you had a MLC, your requests were reasonable. It seems like he is also going through some emotional ups and downs and probably will be for awhile. Separation is hard on both parties. Take care of you and take the time to reflect and really think about what it is you want, how you want to live and what you want your MR to look like.
