Relationship heartache! What to do between now & when I see him? or when I see him?

We cant see each other until 11-weeks - that is if i fly to see him again - if i can raise the money. i have told him i cannot communicate with him anymore because problems are getting out of hand & escalating. i know it is because we are apart & have too much distance - it is stressful - been apart for 1yr but saw each other last xmas. to avoid more damange or pain I have begun to delete his texts or emails etc ... he is angry, making me upset & i am trying to focus on finishing the final part of my uni prac in a developing country! long distance has been so stressful & we have reached our limits. we were close when we were together & i am hoping he will help me mend this when I see him again after uni. we have a 9yr relationship & were engaged. i love him very much. he is deaf - text emails just not working - too many misunderstandings when problems arise. its made it worse for us. how can i mend this when i see him again & what can i do between now & when i see him?
