Being in a relationship with someone should be effortless. Even if there are little disagreements, you should not feel guilt, tense and uncomfortable to talk about your beliefs, goals and desires out of fears of scaring your other half. If this is the case, and you're embarrassed or afraid to be yourself around the person you’re with then it is a sure sign of it not going to work long-term.
You should be looking forward to being with person each day and miss them when you don’t see each other for a few days. If you’re arguing more than conversing, if you’re unhappy more than happy then sooner or later it’s going to end, as such a relationship is not sustainable.
