Vela, it's impossible whether you two can get married. However, it shows that your relationship isn't very harmonious. You both are stubborn and persistent. If you two share the same life goals, then you are likely to be together. However, you both want to be the leader in your relationship. If none of you compromise, then your relationship may not last. What's more, it's more likely that you two prefer to develop your own career. It's nice. But you two should spend time together.

So you two can get married if you handle your relationship very well. Otherwise, you two may not get married.
