If its just a casual sexual relationship, then its normal , every man has it or intend to do it . I have been involved in casual sexual relationship outside my marriage past 15 years n enjoy it . If i ever find out my wife been doing it ill take it light n wouldn't blame her . Since your were pregnant, its likely that he fulfilled his physical desire with someone since you were off the track . But if its more than a casual sexual relationship then lawyer up , fight for your financial freedom n held him accountable for child care and other expenses .

Be aware, if a man steps one leg in different boat ur likely to be left behind anytime . Plan for finance , make a plan to squeeze his money as much as u can . People come n go , feelings are not as important as finance . You can have feelings to anyone but hard to have good finance .

So , if its more than a sexual relationships that your husband is having , lawyer up and cut him right away. Sooner is better.
