Kelela, it's really hard. I remember when W started doing this when our live-in separation began -- constant texting, and hours-long phone calls on the patio every night (that I could hear some of no matter where in the house I went). Eventually I told her that if we were going to live together, we had to make some concessions to maintain the peace and that she couldn't call him on the property - she had to be past the curb.
She probably just called him from the bedroom, but it did set a boundary. I'm not sure if this is a good idea or not for your situation and there are better people here to advise on that.
Until that happens, continue to ignore it and please take comfort in the fact that even if the A does not end, the incessant contact will as they settle down and get into more normal contact routines. It can take a few months to get to this point but eventually it is too much for anyone to maintain, and they grow bored of it as the A novelty wears off.
