Don’t ignore red flags.
There’s a reason why those red flags come up so soon in getting to know someone and although some flaws aren’t a big deal make sure you do acknowledge it and assess it. If there’s more than a few things that make you question him for his action, it’s enough to walk away before you are in too deep. There’s no reason to care, you just met each other. If there’s a few red flags already, what makes you think there won’t be more in the future.
The real compatible person for you will within those red flags also be able to dissolve them.
Know your standard.
How you start a relationship with someone (anyone) it sets the tone of the relationship in the long term. If you allow someone to mistreat you and not mention it to him then he thinks you accept and allow those behaviors and it will continue. But if you mention early on in the relationship then there’s time to work on it. If they don’t then move on.
Know what you expect from the relationship as it develops.
You can’t blame someone for not knowing something. If you feel that the relationship is getting more serious for you, make sure you talk it out. You can then know if you’re on the same page or not. If you’re not then there’s no point forcing a relationship, move on.
Best believe that we all know what we’re getting ourselves into. If you feel like “he is not a relationship guy” you’re probably right because he probably showed you signs. But if you think there’s a shot but you’re unsure then just talk. We are all afraid of facing our own fears but tough luck, that’s the only way you can get through it.
