How do I split a String and keep the delimiters?

I don't understand what my ex wants help me please (long but really need help)?

• well we have just had sex for the 1st time since we split up 2 years ago.we have a daughter together who is 18 months old,she split up with me before we realised she was pregnant. when we first got together it was amazing she was the most beautiful intelligent best person iv'e ever met,we dated for a year and during that year together we saw eachother almost all of the time so by the end the spark was gone as we had smothered eachother.i took the break up bad and we argued like crazy whilst she was pregnant i just couldn't get over the split as from the moment i met her i knew she was the one.she is my world her and my daughter and i just want to care and love them so much. when our daughter was born we began dating for a month but things soon went sour and we stopped.we would go months on end without speaking unless it concerned our daughter as we both our very good parents and we keep our life seperate from our childs as we don't want her caught in the middle we know she is the most important person for both of us and we take our parenting responsibilities very seriously, now the only thing i don't get is during the months we dont speak my ex is always the one to start talking about her personal life even though we would only speak about our daughter during our 'off' speaking periods.the things she tells me are always good news but the last couple times wev.e been on speaking terms she always brings up that she would like to have sex with me again. we usally never got that far but a fortnight ago we eventually did have sex which before we did both agred to a once off as we had nt had sex with any since we were last together.now a couple days later my ex suggested we did it again 'no string attached' we have been at it 2 weeks now all in secret as we don't want our familys to know for now. we are both young and have not really been with any one long term exect for eachother.we have both been with other people since we split but we never had sex with them. my ex is very shy but since we split she began socialising with an older crowd of women,these women are lets say very naughty as their all single and like to have sex with strangers all the time,my ex is not like them in that regard but since she has known then she has turned from a shy.quite respectful girl into one who for months claimed she hated me yet is the one to always speak first. i don't known wheter she is hoping this will help us get back together as when she suggested it this time she said it would make things between us much better, the first time she has said this. now we both agreed all we would do is have sex but she again has been telling me alot about her life and our child in bed. does she want more for me, is she hoping this will eventually lead to us becoming an item again as she has also told me how many children should would like and what age she wants to have them.she has also told me she is looking into getting a place of her own and the reasons why as she lives at home with her parents is she using this 'no string attached as a way of safeguarding herself in case we dont get back together or is she just looking for fun

• Answer:

  This sounds long and complicated to start it off. I know it might be hard but just being friends would be easier. Getting to know a little more about each other would be better than starting at the relationship. It would be easier to take it slow then rush through it or you'll end up making things more complicated. Its really up to you guys. Shes probably trying to figure out whats best for you, and her daughter, including herself.
