<human>: Can you provide a brief rundown of the text in within 3 sentences?

My girlfriend and I have been dating for more than five years. We're engaged now and will be getting married at the end of 2013.

Throughout the first two/two-and-a-half years of our relationship, I smoked weed and visited strip clubs without her knowing. I would smoke about 2-3 times a month during those years, and have visited about 8-9 strip clubs overall (with lap dances). I've never told her about any of this.

I began to feel really guilty about this a couple of days after proposing to her and now I'm not sure what to do or how to feel as a person (am I just another scumbag?) What should I do?
<bot>: I've kept secrets from my girlfriend (now fiancee) of five years about smoking weed and visiting strip clubs and now after proposing, feel extremely guilty.
