5. You struggle to start a conversation, now.
This is one of the strongest indications that your partner might be unhappy in the relationship. If you find your partner not able to interact as often as they used to do, they may not be happy with how the relationship is going.
6. He/She takes forever to reply back.
There was a time you two used to be crazy texting and talking to each other. If you feel you are no longer a priority, something might be up.
7. Your partner is cranky all the time.
Is your partner testy most of the time? If this is the case, then your partner is likely to be unhappy and is not willing to say anything.
