My husband often sends short messages to other women on my mobile phone.

Don't be too smart to be a woman. There is no need to make any changes, and there is no need to feel unhappy. Everything has nothing to do with you! If he was a bad guy or had other ideas, he would never make so many mistakes! Poor and compassionate girls are naive and compassionate. I've been through your experience. The difference is that he and I are transparent. He won't keep anything from me. Under my persuasion, he said those women deserved it! If you can persuade him, persuade him well and do your best, no amount of grievances will have too good consequences for him. But don't be angry, let alone sad.
