You shouldn't be living your life in fear. Both baby and you need a break from each other every now and then. If you decide not to work outside the home, try creating an inside the home work opportunity. Are you really great with children? Perhaps a daycare in the home, or before school care or after school care. What talents, skills and abilities do you possess? My grandmother was great at cleaning so she cleaned houses for a living and my grandmother in law washed and ironed shirts for extra money. I do flyers for events for people and my husband offers studio time to musical artists.
What things can you do with your own hands to bring in money? Try doing that.
I know many have crowned your husband a "a-hole, jerk, etc", however I'm not going to do that. I just figure he has a poor way of expressing himself. Keep things really simple by running in place or doing jumping jacks or jumping with a rope for 10-15 minutes to start. This will help get you jump started with a exercise program.
Think of some of the things around the house you really hate doing. Get him to do them, offering sex in exchange for the house work. If he is unsophisticated enough to threaten your marriage you should be savvy enough to get what you want out of the deal. As crazy as this may sound, men look at sex differently than we do and they really do need it more than we do. Many wise women in my circle have taught me about the importance of sex from the man's position. Many of these woman have been successfully married over 30 years. They tell me that as a wife you sometimes will just need to get yourself in the mood. Sex is also a good work out. So lay it on him real good. Make the time and create the mood.
Your son may seem like he was just born yesterday but he is already 2 and sooner than later he will be living his own life. You still have to develop and foster a loving relationship with your husband. Don't be afraid to speak you mind to your husband and let him know how you feel and what you think while holding him accountable and responsible for some things around the house too.
