Relationship issues..!!!?

i know they say that communication is key but I cant seem to communicate with my bf..i just give him attitude. I have a little monetary issue and i felt bad when he said you can get through this instead of we..yesterday he told me he was sick and went to sleep i texted him to see how he was doing but i received no response. however I went on his fb and noticed he had responded to a post..that had me more annoyed...when i txted him again he responded by saying oo hey I just woke up..lies! little things like that do not make me want to open up and I feel everytime i do and i share my insecurities i feel soft. I am a strong women in certain aspects but not when it comes to relationships. so this whole weekend I have been a complete *** to him..and he's taken it i believe up until now...how do i fix this since it was me who started it without seeming soft?
