Do you consider it acceptable to be in a relationship with someone who hasn't gone on a date with you in a month (or even spent more than an hour or two talking to you) but has managed to go clubbing multiple times?
I had wanted someone to spend time with me.
He was highly busy, which was something I understood upon entering the relationship, but after freeing up multiple weekends and letting him know in advanced that I'd like to spend time with him he kept opting to go clubbing instead. It's not a problem that he went clubbing, nor was the frequency, but he flat out told me that he was too busy to text me while he was out clubbing. Too busy during school okay, work okay...and clubbing...not so okay.
I don't think waiting over 20 hours for a response and never getting one is alright either. I found that to be more him ignoring me.
Trust - I trusted him during the relationship. Trust is very important, and things will fall apart without it. I believe he feels like I didn't trust him though, which probably lead to him ignoring me.
One makes time for the things that are important to oneself.
