Working on limitations

If a relationship cannot give that secure feeling that my next step would not be on a landmine.. its a fake relationship. There is no honesty in it.. no truth.. Its like we are cheating ourselves in the name of that "relationship" . The most successful relationships are those where each one works around the limitations of the other. Not the ASSUMED limitations.. I'm talking about the REAL limitations. This might look a little negative .. but this is a more realistic approach. We strengthen ourselves by what each other know. But what creates the first crack is an expectation surpassing the limitation of the other. Expectations get built around one's ability.. in any relationship. Limitation is the max efficiency one can perform that 'action' that he is able to do. When I say I cook well, you cannot assume me to be your personal "Nigella" . I cannot be your personal ' aishwarya rai' or ' sharukh' or even your personal 'man / woman next door' , who always appears better than me. In a husband-wife relationship, there is an acceptance of the limitations of each other , appreciation & strengthening of the specialities of each other , work within this premise - all happening in a warp of love. Do you feel this is idealistic? It just implies that you are not really HAPPY. Just introspect....
