I don't see a future with DP and I don't know why

[HatePeppaPig]

We've been together 4years have a DD nearly 2 and I'm due to have our 2nd dc in September.
Since I've became pregnant I just don't really see us being together in 5years, when I think of the future I see myself as a single parent and I don't know why.
I love dp and I think we have a good relationship we have our ups and downs like everyone else especially with a toddler running round but no reason or concern to make me think we won't last...
I've always believed we were really good for each other and would last we plan to get married once we've bought a bigger house but I just don't see that happening and I don't know why.
It's making me feel really down I've never doubted our relationship I don't want it to end but at the same time I feel like I shouldn't plan to far a head.
Has anyone felt like this before? I'm hoping it's just the pregnancy making my hormones go crazy but at the same time I don't think pregnancy makes you think of your exit plan 🙁

I would say it is pregnancy hormones and having a young child.
When we have children we realise it's not just about us. Things change a lot. Try to focus on the positives together and bring happiness around you and within the home and don't let that go. If things are okay between you then let it carry on. It is too easy to let stress and busy lives overtake. I think we change and see our partners in a different way too. But it doesn't mean we have to leave and switch. We can just focus on all the goodness and the newness.

Perhaps you're playing out a fear?
What happens if you deliberately change the picture in your head?

Maybe you're rehearsing in your mind, the playing out of a deep seated fear.
Sometimes, it helps to mentally visualise what it feels like to be alone, abandoned, broke, depressed because you can experience the feelings/imagined reality, in a safe space of your own creation.
It's nothing to worry about OP.
Just a natural response to stress, change and fear of the unknown.

Is the problem specifically that you don't think you'll get married or do you think you won't stay in a relationship at all?

I think your brain is doing "disaster rehearsal" due to the pressure you are under with two children to protect and raise. Your conscious mind knows that no matter how happy your relationship w DP is, it is not impossible that that might end and your subconscious mind is making you rehearse that scenario, so it is prepared and to reassure you that you will survive. I do not think this means you have doubts about your DP, it's just a very deep primal survival instinct that kicks in when you're a parent.

When I was first pregnant I started to have vivid dreams about DP having left me, I wouldn't know why but he was long gone and I was managing alone. There would be other stuff in the dreams too sometimes like I had to rescue kittens from being trampled by people at a party or I had to live in a house with insecure walls. I still get these dreams and dc is now a toddler.

While I'm awake I calculate how much house deposit I would have if we split up and what kind of house, and where, I would buy for just me and dc! I do not doubt my DP and we are extremely happy. I just accept this as my maternal brain needing to plan for every eventuality for my child.
