<human>: Give me a shortened version of the text

My boyfriend (24) and I (21) have a some personal issues lately and we worked them all out but I'm still working on getting over it and being happy.
Most days I feel good but others I just feel awful and sad and I feel like being sad may just create more problems with us. I'm scared he'll get tired of it and leave.
I'm not sure what to do.

Back Story:
I became insecure because he was being distant (a while ago) and I looked through his email and such (wrong I know) but I found he was flirting with other girls. We discussed it and moved on and we were really really good for a while.
I was online a while ago and his email popped up and I saw that he was talking/flirting/planning on meeting up with people on the personal ads on craigslist. And also he was talking and flirting with a girl on Facebook.
We had a really big conversation about it and cried it all out and have moved on.
<bot>: Still sad about past issues that have been worked out with my boyfriend. How do I move on faster and just be as happy as I once was?
