Try to speak to him again? He might not understand the extent of what you're feeling. A lot of men are clueless like that.
Around the mid of my 2nd trimester, I started feeling depressed. My hubby is quite a workaholic, and he needs to attend work calls at nights quite often, since he works in an MNC. And when he's preoccupied, he hears nothing when I talk. After work, he would watch tv and fall asleep on the sofa, so I sometimes don't have the chance to talk to him properly.
I felt very alone, because I thought he didn't seem to be that interested, and I had to make a lot of the arrangements on my own (source for confinement nanny, come up with list of things to buy, look for prenatal course, buy my own prenatal nourishment).
There are times when I looked at how he worked, and I worry that I would have to struggle to take care of the baby alone, when she's here. I kept picturing myself carrying the baby, and both of us crying helplessly. Also, my grandma, who brought me up, passed away around then during the circuit breaker period, and it caused me to be further depressed. I cried myself to sleep many nights, and sometimes I wake up halfway and end up not being able to go back to sleep.
It was only on one day when my hubby saw me break down and cry, that he realised I'm really not alright. He got a lot more involved after that, and things are a lot better.
I also agree to seek professional help if needed. Check with your gynae if she could refer you. You're not in this alone, so don't carry this burden by yourself. It is alright to seek help. Take care!
