Ex Girlfriend

Hi guys I'm new to this so please bare with me.

I've been with my partner for 2 1/2 years and we are both in our 20's. I love her with every inch of me and all I wanted was to marry her, but like every relationship there are problems. We were completely fine until earlier this year where I had heard rumours that she was trying it with other men. I over reacted and ended it without hesitation. Around a month past and we met up. We had a good conversation and to cut a long story short we got back together. Now 3 months down the line she has turned round and said she's not happy, my heads not in the right place and I think we should split up. I've tried everything to get to the source of the problem. She said she finds it hard I'm rejoining the military even though she knew it was happening and said she was fine. She has said she is still hurt from what happened on our original break up, she feels trapped etc. She has also said she needs her space which I understand. Anyway this has been near on 2 weeks now and all she is doing is hanging with friends and they are mainly guys. She said I need to stop texting her which I've done, but then sent me a text asking me to go to the cinema with her.

I'm just confused on what to do. I would do anything to be with her but I can't feel like this especially if she has no interest. Having said the she has told me she loves me and is still interested and just needs time.

Any help would be appreciated.

Thanks Tom.
