Used to behave alone - not because we like it; but, after tried, failed, forced then used.
Now, our life / lives are intruded (lovely) - not to think about to do something both together at first place, to act as single by direct instinct or to react promptly without couple s feeling in mind.
No problem at all, it s not a trouble. Our lover will surely understand Rome is not created by one day.
But, if it does really cause some confusion or even mis-understanding; give your heart, please. To illustrate by your actions towards that when it s really a burden - believe that it s nothing but a sweet one.
