Tell the person up front what your goals and future plans are. If they are not close to what other person is looking forward to or plans you make want to reconsider meeting other people.
If you cannot tell the person everything (reasonably) there is some things that don't need to be said. I think if you can talk to someone as a friend and laugh together that is great.
If your bonking heads find out why? If it is something you cannot live with then move on.
You need to find someone that is good with money and does not over spend or have debts. In the future that might not be so good. If they are doing something about and really getting somewhere and not showing signs of doing things that will make things go backwards.
I like to find someone that will take good care of there self and eat right or is open to eating right with you.
Are they fit or a slob or in the middle. Health issues are good to know.
Does this person have the same interest as you?
I told my ex from the start what I wanted and he made it sound like he had the same ideas but later. Well I guess I didn't realize how later he meant. So he did admit that he strung me along as long as he could to keep from marrying or anything else like kids.
Be with someone that has common ground with you and communication is huge. You see red flags ask questions. If you continue to get no where or answers. Move on!!!!
Good luck! Have fun and see where things go. After 6 months decide if this is what you want.
