my boyfriend and i have been dating for 2 years now but recently we've been getting into quite a bit of arguments (mostly due to me being highly sensitive and slightly too emotional); in our most recent fight he told me that it feels like i always have something to complain about him, that he always feels pressured to call me straight after work or to answer my calls immediately otherwise i get upset, and that even though we're not long distance (we usually see each other 1-2 times per week) we always spend hours (usually around 3-4 hours) on the phone and for him he doesn't think it's normal or that other couples do that (i'm pretty sure other couples do that though and for me, i like spending hours on the phone with him even if we're not actually talking because to me it's the equivalent of spending time together when we're not together in person... also i don't get why he's complaining about the length of our calls now when we've done them for most of our relationship and he didn't say anything bad about them). he's also told me that he also wants to have some time alone and some me time to recharge (this is different for me because when i'm with him, my social battery recharges/doesn't get too low). i admit i'm very clingy and i've had emotional outbursts when he says he'll call me but then he forgets (but for me it's just, i'd rather him just not say that he'll call me if he doesn't think he'll be able to do it otherwise it just disappoints me).

now he's going overseas for 6 weeks to accompany his mom to his home country and he's asked for a break cos he just wants to "have a nice holiday and not deal with anything negative". i've asked him if this break means we're still exclusive or if it's a break that we're allowed to see other people and he told me pretty firmly that for him, he won't be talking to other girls but he doesn't want to dictate what i can or can't do during this break and he thinks we should spend this time to work on ourselves until he comes back. he also said texting each other is fine, but no calls for now. he still calls me babe in texts and still sounds somewhat affectionate, but we haven't called for two days now. my question is, is this normal for istps?? i just can't imagine going 6 weeks without calling your partner... wouldn't you feel detached from each other by then? did i overwhelm him by being too clingy?
