2.) Scheduling Conflicts Are you having fun—together?
You should be during the early weeks of the relationship.
When, after several months of dating, he still can't remember what college you went to or constantly forgets that you're a vegetarian, it might be time to reevaluate things.
Either he doesn't care enough to truly listen when you tell him about yourself, or worse, he's confusing you with other girls he's talking to.
Sure, it's just little stuff — things that seem unimportant and are pretty easy to explain away if you try hard enough.
First thing: Consider the source for the lack of lust. Resentments, and guilt can all impact the quantity and quality of your nooky.
Whatever the reason is, confront him about it sooner rather than later. He's showing you that he doesn't value your time together enough to put down the phone and fully focus on you, not to mention that it's super shady — who in his life is requiring constant and immediate responses? But when an adult male is constantly looking to his mom, his friends or even to you for approval before making non-life changing decisions?
A guy who's addicted to technology isn't the most attractive thing to begin with. This is not cute, and it probably means that his maturity level doesn't match his age. You're bound to eventually get on each other's nerves and start nitpicking.
The reality is that he's either still leeching off his parents' charity, or he's racking up a mountain of credit card debt.
A relationship with someone high maintenance can be exhausting - not to mention expensive when they always expect you to pick up the tab.
