My ex and I had/have different values which in end didn't work out, clearly.
While family is important to the both of us, our views on how to raise children and the importance of education and service based activities were vastly different. I am glad that is something we talked about before getting married or else things could have gotten messy. I come from a family where my parents hadn't talked about these things before have children on top of the fact that they both come from vastly different cultural backgrounds - needless to say there was always conflict and my parents rarely saw eye to eye. As such I firmly believe that your views with your partner on children/family should be similar or that reasonable compromises need to be made before hand. But alas my ex and I were on completely different ends of the spectrum on how to keep a household and even trying to find a compromise was hard.
Also politically and morally we were different. I overlooked this many times during our relationship. However, now that we have parted ways I do not think that I can honestly be in a relationship with someone who has different political and/or moral views than my own... Politically I think I can be swayed on, that is if the person is informed and keeps up with national and local politics. I think debate and disagreement on things can be good in a relationship but my ex didn't follow politics yet had plenty of opinions. Morally however, I will not compromise on again. Ever.
Don't misunderstand, I did love him and he is good person, but in the end it wouldn't have worked out. Some people manage to handle relationships where their partner and them have vastly different values/views and more power to them, it is just not something that I can do.
