You are probably missing your cheating ex husband because even though he cheated on you, you may still love him.
Definitely yes
tell him he has a small penis
Not necessarily.
If you have not been having problems with you husband and have no reason to believe he is cheating then a dream is just a dream and there is no clarity to that dream so do not make trouble where trouble may not be. Ifyou have suspected your husband is seeing his ex and cheating on you then the dream was because you have been stressed out about it and if this is the case then you should communicate with you husband (don't tell him about the dream) and ask him if he is seeing his ex. Although most people cheating will lie you can sometimes tell by their body language which is: face turning red; they will not look you straight in the eyes; they shift from foot to foot; they may go into another room or they may deny quite angrily that you are crazy and trying to make trouble. These are some forms of a man who is cheating and is lying about it.
you could believe him and ask about it or you could just ignore it!
Having a cheating husband is already a problem to solve in your marriage.If you try to make him jealous, it will be the result of a second problem to solve.Making him jealous is not a way to get his attention on how you are hurt. He might not be afflicted by what you will try.Communication and Counselling (therapy) would be a good start.
If you have absolute proof that your husband is cheating with this other woman then you should deal with your own problems with your husband first and yes, the other woman's husband should know. This is not an uncommon problem and most people (whether a husband cheats with another man's wife or a wife cheats with one of her friend's husbands) is very common and the victim of the cheating generally does tell the husband or wife that their spouse is cheating with their spouse.
You cannot tell absolutely except by catching them together.
No it is not cheating as long as you were not talking to your ex as if you two were going out. Also you need to tell your boyfriend that you were talking to your ex because how can he rust you if you tell him lies and if he cant trust you that will lead into a breakup
It depends on the people involved
if they are really silent when there by or talks to him alot or flirts with them
