Relocated the family and he dropped the bomb

[MM78]

I'm posting with a minimal update, but mostly to ask advice on what to do next.

Recap: 10 or so days ago I read an email from her to him that said 'i love you' and I responded to both of them (he had given me the password). The following day I drove back to hometown with the kids not realizing my grandmom passed away overnight. My last communication with him was a text to inform him of this and after a brief exchange I wrote 'bye' so he didn't contact me again.

I did take the kids to visit his family twice while I've been here. His mom texted him pictures of them playing at his childhood home. He hasn't responded to her either other than a brief phone call to say he hates himself, his life, and his job.

I have also noticed in the last few days that the texting pattern has changed and she is sending 3 messages for every one that he sends. Something seems to be happening but I don't know what.

Back here, I've been applying for jobs, checking out rentals, going shopping, and keeping busy with friends. Got lots of complements on my new hairstyle and how 'put together' I'm looking lately.

So we have had ZERO contact. My question is that my family is going on a vacation next week. Should I drive home and just show up one night, get what we'd like to take, and then have the chance of having him ask questions. Or do I email him and say I will be home for one night and ask him to get a hotel. Or finally, skip what we don't have, pay a few bills a week late (because they are at the house) and head straight to the vacation. By the time we get back it will be just over 3 weeks since we have seen or heard from him last.

I'm going on with life assuming I'm moving back to my hometown and being a single mom - but not signing any leases or anything official. But it would be great if he wanted to work on things, you know?
