Dear Love Guru,
I am 50 years divorced man in relation with a 42 years divorced women.
We have known to each other for the last 7 years, but only for the 8/9 months we have committed to each other. We intend to marry. But she insists for 40 lakh money and 1 flat in her name. Then only will see agree to marry.
She says if not given she will marry another guy who will meet her requirements. I am so much in love that I am thinking of giving her demands and marry her.  But the real problem is, she has many male friends with whom she regularly chats over watsup and messanger. She also goes for dinner with some friends. 
Secondly, whenever we go to any group parties (her known) she flirt around with male friends, like taking pictures holding each other, dancing closely together etc. I after ask her dance with me or take snaps with me, she just avoids.
I have seen many male friends of her touching her bump or cheeks or holding her waists, she never objects. But when I try to do the same, she objects saying what people will think etc.
She tries to stay away from me during the parties. I constantly remind her to stay with me, she says not to be so possessive and allow her some space. 
Previously we had sex once a month for 5/6 months, but for the last 3 months she has totally stopped having sex, she says will do it only after marriage. Whenever we had sex, she didnt seems to participate, she just tells me to finish off fast. 
Again, I am only one who telephones her every night for talking. She never calls me. Throughout the day she never calls and rarely chats with me.
After I propose or insists, we meet once in 10 days. she always prefers to meet in group of friends. With me she talks quite ok, but in group she becomes very lively and active.
I am confused whether to proceed for marriage by fulfilling her demands. What if after marriage she repeats the same flirteous nature and not so committed towards me.
Please advice and help.
Regards.
