It isn't question that we can answer for you, but we can give you our experiences & you can make your choice based on them.
Here is my story...
In 2001 I left my husband because he didn't want children. He too liked the peace & quiet, the going off on short breaks at a moments notice, etc.
We married [young, I was 20] in 1994 & he had never made it a secret that he didnt want children. At the time though, a 20 yr old, new house, new husband...I wasn't thinking of children. I thought worse case senario our love would be stronger than my desire to be a mum & also hoped in my niavate [sp] thought he would change his mind.
My desire to be a mum was too strong & on suggesting we start a family he didn't want to know & I left for a while to decide what I wanted to do. Not long after I left he contacted me & said that he wanted me home, he couldn't live without me & would have a baby if is what it took to keep me.
Still madly in love with him, I agreed. Once I got pregnant I kept telling myself that if he didn't love/want the baby when it was born I could love it enough & it would want for nothing.
He didn't talk about baby stuff, refused to buy anything, reluctant to attend anti natal appointments etc. I left again, convinced that he didn't want the baby. This time my love for him wasn't enough to keep me there wondering.
After 2 months, I woke one morning to feel baby kicking inside me, I rolled over to say to him "feel this, quick" and cried when I realised he wasn't there.
This, amoung other incidents took me home to him again. Dd was born a few months later, 4 weeks early [I had pre eclampsia].
I look at him & dd [4] now, when they are playing/reading together and I wonder how I came so close to taking it all away from each of them. He ADORES her. She is his world. We had a pregnancy scare at the beginning of the year & he was clearly excited to think that we could be having #2. It was a false alarm, but it was enough for him to ask me if I wanted to try for #2.
I am now 16 weeks pregnant, he is scared at the moment, but as I am...due to the pre eclampsia.
I have since found out that his reluctance to be 'involved' with #1 was him being too scared to be involved. That if he wasn't attatched, he wouldn't hurt if something happened. I don't know the whole history, but he had a younger sibling stillborn & he couldn't help but reflect on that.
I'm waffling...I guess what I am trying to say is that you won't know until you are there, but babies do have this way of making you see things so very differently than before.
We took a HUGE risk, we could've lost everything...but we didn't. We gained a beautiful little girl who adores her daddy [for adores read 'wrapped around her finger']. The teenager thing, well hopefully after spending many years with a baby/toddler/preschooler etc, you'll be better able to live with a teen..YOUR teen & I think that THAT is what makes all the difference.
Good Luck & I hope I have made sense!
