Talk to him about how you feel about this relationship. Ask him, is it important to him to maintain this relationship with this lady? Don't ask why. Be specific about your questions. The reason why Video Games are so addicting is because they allow the users to enter a world that they have complete control over, with no consequences to their real life. Friendships are made quickly over such games with other people who are interested in the same things you are. But I sincerely suggest you talk to him about this, if it truly makes you uncomfortable. Emotional affairs can be just as damaging as physical ones and he should understand that this is bothering you. If the relationship is harmless and you trust him not to do anything and as long as it doesn't take away from the relationship the two of you share, then there should be no problem. Perhaps you should be asking yourself why he is searching for someone else to be emotionally intimate with. Maybe the shortcomings aren't all one-sided.
My advice, talk about it.
**sidenote: what does her weight have to do with anything?
Additional Info:
Further, you mention specifically that this is a BDSM affair. I am assuming you and your husband are not into BDSM in your real lives. Perhaps he has a unexplored desire for dominance or submission and is using Second Life to safely explore these feelings. Of course this does not mean it is appropriate given your relationship, just that there is perhaps an underlying *reason* he is doing other than the one you are thinking.
Take what you said to your husband (because, you know, he's not without blame for this, either), and modify it as you see fit.
if you leave his cheating butt, he is no longer having an affair, he's getting laid elsewhere...you should be healing your emotional wounds and standing on your feet NOT your knees
No
if he is accusing you of having an affair, when you are not.
Yes, that is why he is having an affair.
Yes!
No, it is not a mistake to tell the husband his wife was having an affair with your husband. However, some wives can be in denial and they may not believe their husband is cheating, but most do.
Confront him/her and tell the truth, if you are or aren't having a(n) affair with her boyfried/husband/fiance.
An "emotional affair" is an affair, which excludes physical intimacy but includes emotional intimacy. It may also be called an affair of the heart. Where one partner is in a committed monogamous relationship, an emotional affair is a type of chaste nonmonogamy without consummation. When the affair breaches an agreement in the monogamous relationship of one of the partners to the affair, the term infidelity may be more apt source: wikipedia
You will have to think very clearly about telling your husband about having an emotional affair. Most men do not believe a woman can have an emotional affair and not have a sexual relationship. There is a high possibility that your husband may not believe that when you had an affair there was no sex involved although this is highly possible, but not in his mind. What you can do is learn good communication skills and you must have had your reasons (that clouded your judgment) to have an affair and you need to deal with these problems. Take time to think why you felt the need to have an emotional affair in the first place and then sit down with your husband and express why you are unhappy in the marriage and perhaps seek Marriage Counseling or the two of you could make a better effort with each other to make your marriage a more solid one. Once you have broken that bond of trust with your spouse it is difficult to gain their trust back.
No she is not having an affair. The person she has been calling is actually her husband Ricky. They are using role play.
ANSWER: Even if your husband is an affair material, that will not be his legit reason why he is having an affair. It can't be that he is not getting his needs at home, it will explain why he ask you to marry him if he will betrayed you.
