I have name changed for this, but I'm sure people in RL will recognise my situation.
Bit of background info:
Last year I became pregnant with my beautiful DD after a fling with my now ex-partner. I knew ex for about five years prior to this as we have mutual friends. I was on the rebound and unsure about having a serious relationship with him. After failed contraception I decided to continue with the pregnancy. Ex was supportive of my decision and had strong feelings for me. I had (still do) strong feelings for him but we couldn't agree on most things so I thought we were incompatible. To cut a long story short, we have broken up twice and our DD is only 4 months.
I am in my mid-twenties and ex is in his early thirties. He is also from a different culture. I don't think this is entirely relevant.
The main issue was that I live in a one bedroom flat that I own with DD. My ex rents a studio flat. Initially my ex was going to move into my flat, but after a trial week he found the journey to work too stressful when coupled with unsocial able hours. So he suggested that we rent a two bedroom flat halfway between our workplaces as a mortgage isn't feasible for us at the moment. However, I am worried that I will take a step backwards if I rent. Also, a few of my family members said that it shows a lack of commitment from his side.
We have other issues but this, I feel, is the main problem. We are trying to sort things out after a rocky split. Am I being unrealistic in my expectations like ex has said? Has anyone else been in this situation?
