Lending a friend money,and not getting it back Last year ,I lent a friend alot of money ,he convinced me that he lost his wallet and needed money for certain payment,promising that he will return it after 3 month,he payed some of it  then delayed it to the next year and now he tells me to forget about it till he can return it. 

Now there is a feeling of regret not only because of the money which ,I Lent in expectation of getting it back but also because the friendship got affected . Feeling that he is a liar made me think , I should've been mindful of the deception.As well as not having any compassion for him.

What should be done right now according to Buddhism?.
Next time better simply give, never expect something return, for bondage is seldom a help for both, all involved. If not able to give, that's "fine" as well, but never lend. Even if now saying "no need to pay back", for example, your friend might be even more lost.

My person did, after doing such one or two times, never gave loans and it makes/made much more on releasing joy to simply give when asked and able to, and never even a little regret in don't giving loans but make clear liberal gifts.

Now what to expect? Just let it be his good and proper or demerits? If possible to bear it. Would be one possibility: patient. Things are at least not for sure and giving, even if time and place to get back on good track, is always good.

Much joy in wise and liberal growing. Joy in giving without intended on a deal or back of low and material things.

(Note that this is not given for trade exchange or stacks, but to turn toward freedom from bound in loan giving because of debt)
