Boyfriend problems .

I need help from you lovely ladies . Me and my boyfriend have been arguing so much latley it's redeculess iv been with him for a year and 2 months now and I love him we been through so much I got pregnant by him and had a misscarrige at 3 months but it's been 6 months now since that happened if I was still pregnant this July I would've gave birth .. I'm over seas with my family away from him it's been 2 months and I feel like my relationship is dying of .. I love him so much but he's been doing things that's been bothering me we used to talk it out he used to care more and show me more attention it's those little things you know also chase after me it's like I'm doing all the chasing and the fighting . I don't wanna let go but iv thought about letting go but I just can't let go it's hard for me because I always have hope he'll be how he used to be .  I'll be back in 2 weeks do you guys think it's a distance thing or maybe he's losing feelings ... Iv asked him but he denaies it I don't know what to think anymore . It would be great if you lovely ladies could give me tips on your relationships or arguments or it's worth it or whatever it is just need some help .
