I could use some help? thanks:D?

I'm In a band and for A while one of our singers/rythm guitarist hasnt show up, only occasionally, so he's I guess kicked out, at least that's the way It seems. So the rest of the band has been doing our own thing together and it's not a big deal, I just think the writing's a lot different and A lot more has changed than anticipated. I don't really know what to do but I'd Like better songs and just things to progress agin. What should I do? I'm sorry If this is confusing, but thanks[=
