Hope i will be able to help....or hopefully someone else can chip in to be able to unlock the tied knot in your heart....but hope you don't get devastated whatever it is.
First...as a buddhist....you should be able to accept the theory everything happened for a reason. Causes and effects.
Couple or people get together according to their own karma link. As of now....your partner may have not arrived. Maybe they will come a later stage....and perhap this is a blessing in disguise for you.
If you can minimise your desire for wealth( or did you just give up because it is not practical?, note that these are two different things)...you should be able to minimise your desire for a partner using the same method. Unless your way of minimising the desired is wrong but perceived that you had done it successfully...then you need to revisit the method again...
Chanting and meditation is the only way to help you end all suffering.
Chanting with great mindfulness allow your mind to be focus, pure and thus able to radiate loving kindness(good wishes) to all beings. This will bring more affinity with others. Perhap in your past lives you had been a monk or priest with no desired for love...thus it does not create a karma link with the opposite sex. There are more other reasons....but dwelling into that won't help...so lets move on below...
Meditation train your brain to be less disturbed when you encounter all undesired situation(such as your case )....many says it don't works and it only works during that half to one hr of practise..and once you are off meditation and confronted with situation...it is still easy to get frustrated.......so my question is? How often do you meditate? How long do you meditate ea time? Since when you start meditate? If you only started few years back and meditated 10 -15 mins every day or sometime skipped...then how do you attain peace easily? So how much is enough? I won't and will not answer this question. Why? Cos everyone are borne with different stage of mindfulness(ability to focus ) during their birth and thus everyone progress will be different....even buddha in his last birth takes years to meditate, and go thru all the suffering before total wisdom arised and able to share his discourse. So you sure you have practise correctly and successfully.
Note that desired come from inner heart and only self help will help with good advise from anyone ( your affinity).
- When the ear hear noise, thought arises and thus is good /bad feeling. So how? Stop the noise at the ear.(acknowledge sound, sound, sound...)
- When the eye see form, thought arises and thus is good/bad feeling. Stop the sighting at the eye.(acknowledge seeing, seeing, seeing...).
- When the nose smell thing....etc etc
- When the tongue taste thing....etc etc...
- When the body feel thing ....etc etc....
When it is too late and the sensation get into the heart (mind )...acknowledge whatever the feeling, sensation is...and let it go....it will take many practises before it become a habit and thus easy to end unnecessarily suffering arised.
