<human>: Condense the text into a few key points

After a year and a half, me and my gf went through a heavy discussion about our relationship.

Thing is there are 2 problems:

1) I am too clingy.

2) She has trouble communicating in a mature manner.

3) (addon) the combination of 1) and 2) creates even more bad situations: she doesn't communicate her problems to me -> i act clingy thinking i can help her being more with her -> she feels smothered and so on..

Since this issue was brought up in the past but we never fixed it, the discussion started with a fight, then we calmed down and kind of felt sorry for each other. We kissed and hugged like we usually do. But i felt in the first place that we need some time to think about our mistakes and that it's something that cannot change from a day to another.
We decided to "wait for a while".

We left in a very affectionate manner, she was all hugged to me on the drive back to her place and kissed me tenderly the whole time. We ended the night kissing each other as usual with a smile on our faces, but we are officially in a break, so we won't be hearing each other with the same frequency we usually have, or we won't be hearing each other at all.
I am now trying seriously to work on my issue.

I am taking back control of my life with little steps and i am trying to become a better person, for me, and for her.
I am asking you guys what you think about this and how would you live the situation? There is hope after this or are we wasting our time?
<bot>: me and gf have 2 problems: i am clingy, she can't communicate. We love each other but feel like a break is necessary to fix things about ourselves. How can i handle this? It's worth it?
