Should I give up or still hold on?

I need your advice. My boyfriend and I are really on the same page. I love him so much. I don't see anyone in this world with me but him. But, I feel so different lately. So he's on vacation from work. He's in the military. He first visited me and stayed with me for 2 weeks. Then, he went to the states to visit his first son for 12 days. But after that, he went to Italy to visit his second son. He's been staying there for 2 weeks. But then he said he'll be extending for a day or two. It's ok because it's for the son. But he's acting weird. He doesn't text much and call both voice call and videocall. It never happened before. Only this time that he went to Italy. I confronted him several times but only to tell me that he has too much on his plate and he's in a bad situation now. I really understand our situation. But I don't feel good about what he's doing. The extension, the not calling and texting much and I feel like he's not telling me anything. I got to the point of begging for a little time for me when he's not with his son, but nothing happened. I got to the point of getting angry and he just told me I'm being dramatic and I needed to chill and stop thinking crazy stuff about him and the ex. But I can't help it. He's always at the ex's house spending time with his son. The ex works at home. It's been almost 20 days and I'm sick and tired of arguing. I really miss him. I really tried my best not to think of crazy stuff about him and the ex. I really love him but I don't know where my place is at in his life now. He said I'm just thinking too much. He just wants me too be patient because he has too much on his plate. But, I'm hurting right now because I'm experiencing something bad for the first time because of the decision we made last time. My body isn't well now but I don't feel like he's being there for me. He said he's worried about me but I don't feel it. I'm in the crossroad now. Should I give up or hold on? I really don't know what to do.
