<human>: Okay so I'm going to try summarise my relationship as shortly as possible. 

So i've been with my girlfriend for a few years now, and whilst I certainly love her, the last year has been rough between us and she has now broken up with me.

For the last year she's lied to me, broken loads of promises (started smoking), made out with guys when we were on a break and each time I felt like I was lecturing her and I felt like I was the only one trying to make the relationship work.

I went on holiday and she whatsapped me and we talked and she said she doesn't feel like she's been taking this relationship seriously this last year and she wants to break up. This makes alot of sense. I feel however that our relationship simply has progressed from the puppy love stage, to the serious love stage and we were still acting as if we were in puppy love, which we have both become sick of.

She says she dosen't get excited or feel butterflies anymore when she sees me, and hasn't felt romantic for a few months now. What's more now that we have broken up she says she's stopped thinking about me as much and has stopped caring about "feelings and love and stuff". She's also acting quite cold towards me on whatsapp, although I'm not sure if it's an act or she's just trying to make it easier for the both of us.

I still want to be with her as she was my first and I was hers, and I feel you have to work on relationships, so therefore I don't want to just give up easily. However I am a realist and I realise the relationship might be past the point of saving.

Anyhow this is where I need some advice. We've decided to be 'friends with benefits' for the time being and I am going to hers on Wednesday. How do I behave? Do I act nice towards her as I have always done? Or do I act colder and matter of factly?

Is this relationship over for good, and do I basically not have much of a chance to win her back? If I can what is the best tactic?

Thank You
