I need your advice! Plz help me!!?

So I've been with my boyfriend for about 9 months now and hes the love of my life. He is an amazing guy. We've always had some communication problems but now things have been getting a lot worse because he's off for business this summer and the job has taken him far away and we cant visit eachother because neither of us can afford it, but I'm going to see him in August when he gets back. We've been fighting so much lately and I brought up breaking up with him, even though I don't want to. Just because this whole long distance thing hurts me a lot. How can I stay strong through this? Can anyone give me any advice? Thankyou so much!!
