This is "normal," typical behavior for an insecurely attached person, but for a securely attached person, it is not normal. A securely attached person is able to co-regulate (with another person) and return to baseline in minutes or hours. An insecurely attached person doesn't know how to co-regulate, and withdraws to self-regulate. Self-regulation (also called auto-regulation) takes an indeterminate amount of time, days, weeks, or months. The technological aspects you mention (Snapchat, texting, etc.) have nothing at all to do with this pattern. The question for you is, do you have a secure attachment strategy? If you do, it's better to work on developing relationships with other secures. The fact that you got involved with a person who is likely insecure suggests you might be insecure as well. In that case, a relationship is problematic, but with a motivated partner, you can work within a relationship on your attachment conditioning to eventually provide a more sustainable and satisfying life. EDIT: In other words, here's your chance to learn your own attachment style. Knowing your own attachment style helps you make informed decisions on which relationships to pursue. Don't rely on online quizzes to discern your style, they are often wrong, and certainly not definitive. You could start with a book, Attached. If you are already seeing a therapist, ask about their views. (Although, many therapists have not trained in Attachment Theory.)
Attached by Amir Levine is a good place to start. Gives lots of practical tips on how to work with the various attachment styles
