Ugghhhhh

So me and my boyfriend were talking calmly about me starting school in a month, he keeps asking me well how am I going to pay, like if I’m gonna pay when I go finish my enrollment next week or so I go the first month and then pay so I tried to explain it to him, mind you he’s asked me this 3 times these past few days he’s constantly asking and I try to clarify to him, well today I let out a sigh of frustration, because I keep having to explain this to him, and he tossed the phone at me and said “you know what fuck you, why are you getting pissed at me for asking a question” I responded calmly “I’m tired of having to explain the answer to you and you still not understand” he said “fuck you” and walked out of our home. It seems as if the arguments are getting more frequent and are starting to get worse
