The gf/wife to compliment other men (not their bf/husband), this part sound like a disaster in the making but it is not something that is within the bf/husband's control. If one day the gf/wife notices something wrong with their relationship because they are complimenting other men, just revisit this parameter. I could be wrong or right but my intuition is telling me, I'll be 100% right for most cases.

1)Single female complimenting the male:

Was it purely due the way/words of complimenting, that leads to the misunderstanding or it could be something else ? Would you be able to eliminate the other possibilities and arrive at the point? If you can't, then why focus on way/words of compliment?

What about the sample of the men that have misunderstood the compliment before? What were their characteristics ?

I rather believe it should not be the first time, not 2nd times, more likely multiple times. Whenever the undesired outcomes took place, there is tendency to adjust the input parameters and expect the change to the outputs. If the inputs keep changing but the output remained the same, the reason could be point to the constant parameter, not the variable parameters. The constant parameter, you need to find it out yourself.

If I were female, I'll not give any room for misunderstanding. Don't compliment, you will totally eliminate the possible trouble. There are other way to spread the kindness & uplift man without having to be directly doing it.

Just an example how to spread kindness indirectly based on what I can recalled. An individual (said the mother / wife / gf), visiting the prayer house / temple for offering/prayer earlier in the morning. The prayer house / temple 's keeper is someone who know the family in person. Later when the son / husband / bf come to prayer, the prayer house / temple keeper can verbally tell the son/husband/bf "Your mother / wife / gf was here this morning, she praying for you".  Uplifting ppl can be carried out indirectly just like the act by the prayer house / temple's keeper.

Another alternative, if the single female still want to compliment the male directly and cannot find way to do it indirectly. Stop when you notice there is fluctuation of emotion (provided you can sense/feel the emotional fluctuation). The fluctuation of emotion is the sign of the trouble being born.

2)If the gf / wife is complimenting their bf / husband:

When you are spending the time together, secretly take some photos of your bf/husband without them noticing. In near future, when you notice your bf/ husband are in stress or demotivated mode but you can't be there or you don't know what is in their mind and you don't know what to say, just post their photo that you secretly took on your FB / Instagram stories & tag them. This simple action without having put/say any word has multifold positive effects. It implies you are cheering for them silently in a very genuine way. Some ppl is fully aware, it is just too hard to put the words/ say something hence use the visual as the substitute to represent words. "A picture is worth a thousand words".

This one strictly for those in relationship within their relationship.

3)The male blushing when being complimented

For the majority cases, ppl can generalize blushing reaction implies that the individual is attracted to you physically but do not eliminate the possibility that you could be dealing with hyper shy individual, who can blush (almost everything) even among the same gender or with the elderly ppl. If such individual can blushes among same gender or with the elderly ppl, you cannot use the same reason & conclude that, this individual attracted to the same gender or the elderly ppl - no, they don't. Such individual can blush as long as they are caught in surprise/unprepared scenario. Such ppl exists among us in the society, just you have yet to have chance to meet one it doesn't they don't exist. Both female and male version exists.

Yet you continue to dish out compliments like the "banana currency", at the same time complaining being misunderstand by ppl.
