IAM CONFUSED!!! NOT SURE IF SHE SINCRELY LOVE ME (Page 3)

Iam 39yrs old, reside in Toronto,Canada. I traveled to Naija in July came back 2wks ago, during my visit to naija, i met a lady that we had been talking on FB , along the line we were both in love, she introduced me to her parents and i did samething too. Throughout my stay we were always together everywhere even in her office.
One thing i discovered was that, she had more male friends than female friends whom they were always chatting on FB,she gave her phone nos out easily thereby giving room for lots of text messages coming in almost every 5mins from diffrent admirer. i dont feel comfortable with that because im a private person, easygoing,gentle and down to earth, i told her but she gave excused that there is no any string attached ,eventhough most of them are her toasters.
I tried my best for her finacially, i shower her with gift,as she is now been envyed by her friends and collegue.
My concerns are:
1.she enjoyed chatting with toasters
2. she calls me sweetheart,darling,sweety,etc,only when we re together but not in public,
3,we both agreed to get married by xmas dis year, but of recent i dont see any exitment from her as she was now suggesting that we should postpone the wedding plan,as she is not fully ready.
My confusions are:
1.Both parents had started discussions and planing for the wedding,
2.some of my family members and some of my friends has some reservation about her non-chalant and lukeworm attitude towards the marriage issue.they dont trust her fully, maybe she had a hiding agenda (boyfriend)
3.she always complained about the distance,the age diffrent (she is 25) at the same time she doesnt want to see me wt any other lady.
PLS, people i need your opinion.
Did she actually love me? did she really wants to marry me?? will she be able to be a faithful wife (considering the nos of toaster)
