Why is my ex fiancee acting this way?

this is a long blurb so please bear with me. we broke up in the last of sept from a misunderstanding on my part. i tried to apologize but she said she cant right now too much has gone on. she said stay away and work on yourself.so i did just that. I started my own business that is going good. and I havent calle or tried contacting her. I heard that she started dating a guy in mid oct. fast forward to nov.she starts texting and calling my 15 year old daughter asking her if she still wanted something done to her hair. and asking her to call then when she didnt answer she tries calling my ex wife still no answer but she left a message to call her. during that time I had installed a myspace tracker on myspace and i see that she is visiting it every few days. fast forward to the day after thanksgiving she calls says she just wanted to see how how i was . and played 20 questions with me . I asked about the boyfreind and she admitted yes she was dating . i asked her if he treated her better than me she said he treats me ok. then I said i was hurt that she dated again so quickly cause i would love her till the ay I die. her voice got scratchy and i heard sniffles. i asked if she was crying she said no and said he had to go and hung up. so Itried to call twice and no answer she texts me please stop calling me. so i did. 2 hours later she calls me back we talk for 25 minutes about small things kids job my store. then she gets a call and says she has to gobut asked to call back and keep in contact. all is quiet for a few days then she runs into my mother at the doctors office my mother was cordial and spoke saying I hope everything turns out ok. then 3 days later on friday she shows up at my moms house out in the country after taking her kids to school . why go to my moms? she said she wanted to tell my mom what the doc said . and then proceeded to ask my mom 20 questions about me.how i was all that stuff about my new business. then on sunday nite she calls my mom to ask her if she knows the name of the guy who fills her propane tank cause she smells gas, ok why not call the number on your bill or ask your neighbors or new boyfreind? ok here comes the shocker monday morning im in the shower my phone rings its her no message left. 10 minutes go by she texts me "what are ya doing for lunch?" i reply no plans yet. she calls back immediately and asks to come see me and my store and go to lunch . I agree. when she gets there i show her around and we leave to the mall for lunch small talk about kids ensues . we get to the mall and she goes in a clothing store. and asks my opinion on everything if it would look good on her and do I see anything that I think would look good on her. we go to lunch she picks im figuring fast foo she says bennigans so we eat. after we eat she asks."your incomfortable that i came to see you arent ya?" I said "yes I am because im confused why you came here and im still hurting very badly. she said I just wanna be your freind your a awesome person and i care about you. I said I dont think I can be a friend at this time it hurts to much she started to cry and we left. in the car she says it was mistake to come here im sorry I dont wanna hurt you. I said then please leave me and my family alone and let me heal. she is bawling hysterically now. so i keep quiet . back at the store we go inside my office and I ask for a hug cause she looke like she needed one. she put her head on my shoulder for a second then pulled back quick. started crying again. I asked "why did you really come here today?" she wouldnt answer but seemed like she wanted to say something. still crying . I asked her "I just wanna know one answer for the rest of my life do you still love me?' crying she says she cant answer that right now. and says im sorry I just wanna go home now. I walked her out to her truck and leaned in and gave her a kiss on the cheek and told her these words" I love you with all my heart I want us to be a family again I wanna marry you . I dont care what is behind us i wanna stert over " she left crying so i try to call 1 time no answer she called back in like 10 minutes she listened to me talk for about a half hour not saying much just listening i told her that if she wants to be friends that I cant right now maybe down the road. that i still have dreams of marrying her. than I asked her that question do you still love me she started to cry again and said I cant answer that right now . and she hung up no word since. so what is going on here I know this was long and with bad grammer. but im a lost confused man with a lot of love for this one woman. a woman I would die for no questions asked so what is she up to thanks so much Ibear37
