Relationships are a struggle for me because I don't know how to react to strong emotions
It does sound like a real struggle. What would you prefer to do instead of reacting?
I would feel more comfortable by keeping the situation  emotion free and taking things as they come
Even if you aren't comfortable talking about emotional things, it is expected that in a relationship you will be at least somewhat emotionally available. It is good to know your emotional limits, though, even if you know you should stretch them some.
I would love to be married but I think real relationships that aren't based on strong emotions are only told in T.V. series.
You should find someone who can help you learn to express and react to emotions. They are important in a relationship. Strong relationships can be found in real life, but they take a lot of work.
