HEEELP

So me and My bf have been dating for 7 months today and i really love him. Sometimes though, he doesn’t respond to My texts even though i can see him om the snapchat map. Since My last period I have gotten more comfortable w/ ”showing My emotions” (Getting angry and antingen out When I have pms). Its not bad angry just irritatated, and now hes starting to do the same back. I do know he loves me bc he tells me often and his Friends says he really do but sometimes i just feel really insecure.. does anyone know what i can do to feel better?❤️
