Can I save my marriage? (long; please be patient)

[MadeToSucceed]

Went to get a massage at 5pm today. I'd left my computer on and signed in to skype...when I came back at around 6:15pm tonight my W had sent me a message (timestamp was 5:11pm) that said nothing more than "Hi."

I responded around 6:20pm and said "Hi" but she was probably sleep by then. Not sure what to make of that. She's messaged me on her own fruition twice today. That's a first...in a long time. Gotta keep pressing forward though. Still so early in my process (only 3 months in since it began) that I don't want to get too up or too down over these kinds of things.
