helley did this new relationship start when you were still vulnerable with all the major changes in your life happening too? if it were me, i'd try to focus on the job replacement which could take the focus off the bf situation and you'd be productive too. i was overqualified in a new job search so i toned down my resume somewhat..it got my foot in the door and at the appropriate time during the interview process i tooted my own horn, modestly of course. landed a job that met my qualifications as a result and obtained an increase in salary too.
as for the bf, perhaps his trip brought more devastating news and he's dealing with that right now, idk. i'd only send one (more?) text or email just saying i hope things were going well and since i didn't know the circumstances i wouldn't communicate anymore and leave it to him to contact me. if you hear from him, great! if you don't hear from him, you have your "answer" re him. that's what i term, "next!!!"
just me but you need time to just deal with your life changes, sounds like you are doing well with that right now, and not take the focus off you. if you take care of the little things, life has a way of taking care of the rest.
