My marriage is ending

I've been married for five years. Over the last 6 months I've discovered shady little lies here and there. The other day my husband told me he was running errands but then I found a receipt in his pocket that proved he was actually put at a bar. When I called him out on it he became very defensive and before I knew it, he was asking for a divorce. It breaks my heart. There's so much more to it than my brief description but I'm too tired to get into it.
