Food for thought: The one who moves mountains starts by carrying small stones.
Ever since my partner started his own business, we have been arguing a lot. The conflict is mainly about the fact we don't spend much time together right now. He works every evening and is either too tired at weekends to do anything together, or he is working. I sit at home with nothing much to do, and get increasingly irritated. Occasionally when we do go out, we get along so much better. What can I do to sort this out. We do love each other, but it's not looking good the way things are.
It appears that you and your partner have very different priorities at present. He is focussed on getting his business up and running. Perhaps he has stepped out of his comfort zone to achieve his dreams. What you express about your own frustrations is that your life has little to challenge you at present. You can either sit there and be unhappy, or get up and do something about your current situation. Write a list of options that could be helpful: everything from leaving this man, to getting your own passions into reality, with all options in between. For example you could go to courses on the evenings he is away and enjoy life. Shift your thinking to looking at what could be the advantages of you having so much time on your hands. It is amazing how attentive a partner can become when we find fun somewhere else.
