I hesitate to answer because of being such a rank newby. but my *feeling* is that you should communicate as much as possible...text, phone, ESP, whatever you can...always pausing to make it as complete as possible and address issues as clearly as you can.
expect issues of jealousy, discomfort, maybe even anger and frustration but try to discuss the specific reasons for those feelings rather than the feelings themselves.
Wife and I have Guidelines more than rules, and the guidelines suggest face to face meetings, much texting, and chatting between everyone before we launch into a physical relationship. but we've also discussed that a face to face is logistically difficult given our separation, so other forms of communication will have to fill the gap.
