Most times we forget that our partner is a separate entity. We forget that they too have their own plans and unfulfilled ambitions. It is our job to encourage them to find their path, to realize those ambitions, to stretch themselves to their fullest extent,to be complete and satisfied and fulfilled.
It is not our job to put them down, ridicule their dreams, belittle their plans or laugh at their ambitions. We are not meant to discourage them, put them off, place obstacles in their path or restrict them in any way. It is our job to encourage them to soar.
The more freedom you give, encourage or tolerate, the more likely they will be to reciprocate and return. If your partner feels they are encouraged and trusted, they are much less likely to stray because they feel caged.
The more supportive you are, the more they will feel they are being treated kindly and that is a good thing. Please be supportive, be prepared for them to be independent, strong, out in the world separate from you.
