divorce or nah?!

I've been faithful to him since I was 18. we've been married for 10 years. I'm 28. and we have a 4 year old little girl (with him). our marriage has been on the rocks for a while,but it seems like the ending days. I'm trying to hold on for our family. but I don't think the love is there. in fact I don't think it's ever been there (on his part). he shows me no respect and we can't communicate together. I trying to hold off on filing the divorce papers. I've never been alone before and I don't believe that there's anyone for me (to start over with). what should I do?
