How do you find out if your boyfriend is still into you or if he's wanting to end the relationship?

My boyfriend of 10 months is always trying to get away it seems like. He goes off and plays video games online ignoring me everytime. He asks to be alone to hangout with his friends. So i ask him to please call me in an hour or 2. He never usually calls. So i txt him asking him to please just call for a minute to see how his video game times going and ill talk to him in a little bit. He hardly ever calls. Then he always goes off to his friends house and turns off his cell phone for several hours. On day he even stood me up for a dinner date at my house. I tried so hard to make everything romantic, and he never called. The next day he called and said he was leaving his cousins house and he will come over in just a few. The reason he didnt call was because it was raining and flooding at his cousins house. He just seems to be distant more. Sometimes he doesnt even say i love you back to me! idk whats going on?How do you find out if your boyfriend is still into you or if he's wanting to end the relationship?
You have to have a conversation with him. It needs to be serious, open, and honest. If the love is gone, you don't need to fight or be hurtful. Just let go and wish each other a good life.
