Advice/Nexplanon

So to make a long story short, i’m 18.

i’ve been with my boyfriend for two years and we’ve been through a lot and we’re always together which sometimes isn’t the best but he goes through a lot at home so when i’m not with him i guess he gets upset and acts it but it always turns into an argument. obviously i wanna be home with my family but i get scared because i just wanna avoid arguments.. anyone have any advice on how i can explain to him i wanna be at my own house and have my own time too ? Also, i’m really emotional and i’ve also had nexplanon birth control for two years now and since i’ve gotten it i’ve noticed a difference in my appetite and because of some things i’ve been through i became really depressed.. me and my bf got into a fight and didn’t speak for about 2 weeks so i was home and i was okay and eating so much and we talked things out and i came to his house and since we’ve started talking again, i ate a lot the first couple days but now i’m not eating anything again.. does anyone have this problem ? loss of appetite after getting nexplanon ? i know it can also be from all the stress.. 😣
