Communication during break?

Im in the complicated situation with my boyfriend. We are together for 4 months and Im almost 20 and he is 27.
7 months ago he broke up with his liable girlfriend who threatened to commit suicide if he will leave her…they are still in contact because she hasnt got no one except him and he told me about her at the begging and he told me that if its bothering me or something he will cut her off fully and block her for me but i told him that its okay because i felt pity for her and she is from different country so i thought i wont mind him talking to her in friendly way but after his confession to her that he is in love with me she went mad and she started to threaten with cutting herself. He was so hopeless and he couldnt do it i understood that i know he feels responsible for her but then she started to call and write to him nonstop and i felt uncomfortable because i felt like he is prefering her and my last relationship was really toxic and abusive so i dont really have trust in men and i have my scars and issues. We had a bad fight about it and he said it will be gone when i will come for the next time but when the time came he wrote me that he cant do it right now and that there is too many things on top of him and he cant continue like we had before and he needs a break to get rid of these things and get himself out of this black hole and he doesnt want me to go through this and that he is no good for me right now and i deserve better one..i replied that i respect that and i will give him the space he needs but if he wants to break up he can tell me but he texted me that he is doing this to prevent it and he doesnt want to ruin it that he loves me and cares bout me. Ive met him 4 days ago because i took him his documents for work by accident so i had to give it to him and he started to hug me and kiss me and he said that he wont need that much time that he misses me and i told him that its okay and he doesnt have to rush it, after our goodbye he wrote me that he still loves me so much and we talked a little. Now is our conversation poor and we dont communicate that much. He has work i know but i dont know if he lost interest in me because he was texting me all the time before. everybody is saying that if someone loves u they wont make u wonder. Why is he telling me that i deserve better one? I know he feels bad and guilt towards me but he doesnt want to let me help him and solve this problem with him, he doesnt want to see me because the idea of it seems overwhelming for him right now. I dont know what should i do right now. I dont know if i should be warm and text him sweet or keep distance and short messages.
