[quote] How can I plan a future w/this person?[/quote]
You can’t.
I’m not sure how long you dated him before you married him, but if you didn’t know who he was, and what his character was like, you do now. He sounds like he’s going to be emotionally abusive to your son, and for this reason, you need to admit your mistake and get divorced.
Before you get involved with anyone else, you really need to know them very well and make sure that they are someone who is going to be good to you and your child. Dating as a single parent and re-marrying with children involved is a lot different than “regular” dating without kids in the picture. You have to be super careful because whatever decisions you make, the children are affected.
I hope this helps. Please let me know how it goes, and follow me @AskAprilcom on Twitter and on Facebook at this link: [url][/url].
