Your husband's recent behavior could be due to the fact that you're living with his parents. Men get a sense of pride from their work and their accomplishments, he may be feeling a little insecure because he's living with his parents and he doesn't want you to think he's a failure. My sister and her husband lived with his parents for awhile, and she noticed he acted differently. He would pretty much do whatever he wanted and ignore my sister sometimes. He acted like he did when he lived at home when he was single and had no cares. I think its a mental thing, living in his parents house reminds him of having no responsibilities, intimacy or PDA under his parents roof (we were always taught that was wrong) may be awkward for him. You also mentioned you were pregnant, (congratulations!) Do you remember your husband being distant or weird towards you during your first pregnancy? Thats another mental thing, my husband was not very affectionate when I was pregnant. As for the computer games, you really should try to get him away from that. Otherwise he will become obssessed with them, if he's not already. Playing games occasionally or just for a little while is ok, but not constantly and for long periods of time. He should be spending his time at home with his family and offering to help his parents with anything. Pour your heart out to him, let him know that you feel ignored and you need him to be there for you, especially since you'll be having another baby soon. Ask him if he feels insecure about living with his parents and assure him that its ok and you don't think any less of him. Remind him that he's a lucky guy, he has a loving wife and child, another one on the way, parents who love him, he's got it pretty good! Try as hard as you can to be positive and be there for him too, you might start to see some changes in him. Also I highly suggest you and he get a babysitter and spend some time alone. Go out to dinner and a movie or just take a walk together, it will give you a chance to talk. Above all, ask God to help you and your husband, marriage really does take three to work! I hope this helps you!
