I am eight months pregnant, and have a 2-year old. I have been married for 5 years, and have been with my husband for a total of 10 years. My husband and I have had very few problems in the past, very minor little things.

The past 6 months have been wonderful, though, as we have truly been working together as a team. He has been so thoughtful and helpful, and just plain nice to be around, that it has been the happiest time of my life.

Three weeks ago, his behavior started to change. He became withdrawn, sleepy, and almost hateful to me and our daughter. He shaved, and started complaining about his appearance. I tried to figure out what was wrong by gently asking, suggesting, and trying to be supportive.

I found out that he had dinner with a daughter of a friend right when his moods became strange and neglected to tell me it had been just the two of them. I tried to once again, gently ask about the situation, and he became extremely defensive, saying things like "That's what you always think!" Which seemed a little bizarre to me- I am not like that.

Probably unethical, but I do check his email. He has emailed her several times with career advice. The emails do not appear to be anything but friendly. She has only responded to him twice with thanks for the information. I have checked the cell phone logs, redialed numbers, everything investigative I can think of.

His behavior has yet to change, but he confessed that he is depressed, and he thinks it is because he has not felt very close to me because of the pregnancy. Another time, he said he was depressed because he missed the carefree days of college (we have been out of college for 8 years).

With all of these excuses, I don't know what else to think other than that he has a crush on this person or is having an affair. My father had an affair when I was in college, and I definitely recognize these signs from that experience. I am very worried- with the pregnancy and caring for 2 young children, I am not sure that I am mentally or emotionally equipped to deal with this situation. I would just like it to stop. I can't say anything else to him about it because it just puts him on the defensive, and blaming me for things. It seems like all I can do is wait until I catch him doing something bad, or I know that he has stopped. He'd be a fool to leave me- I take care of everything- bank accounts, retirement plans, medical, etc.

What can I do? I am just praying and trying to remain sane for my little ones. I really feel like my toddler senses things are not right- there have been many temper tantrums since my husband has been acting strangely. HELP! :confused:
