<human>: Could you distill the essence of the text into 1-3 sentences?

My wife (39) and I (34) have been married for 15 years and we have a child together. A three year old daughter. Ever since we had our daughter things have not been the same between us. We are much more distant and we almost work together like to separate people living together. We do not really have that great of a romance.

We have some sexual dysfunction that is mostly due to me (pe). I have been working on that for years and am not getting much better. We are Christians and we do not believe in divorce and I especially do not. However I am realizing that we do not have anything in common as far as hobbies or really much. 

She has also had a weight problem for all of our marriage and constantly complains that she does not have time to work out because of a few reasons. However she is not really trying that hard with her eating. I am not suggesting that I am a model but I have lost 40lbs over the past six months and I am really trying. 

We both go to a great small church and do like going. I have never even thought about cheating on my wife and I believe that my wife is in the same boat as that. However I did find a vibrator that apparently she has been using for three years. Guess she never felt the need to tell me.  I come from a family of divorce and I am not interested in that but I feel trapped. I work full time and she stays home. Am I overreacting to the vibrator? I somehow feel like that is cheating even though I know that's stupid. I told her that it would not 've healthy for bus tourney to have another child while she weighs what she does. I am hoping that motivates her. I probably left some important details out so if you have any other questions please ask.
<bot>: should I be overly concerned about my wife's vibrator and what amount of effect is normal on a marriage with kids?
