We've only been together 7 months. We both met via the internet
I caught him out with an online profile at a site which stated he was single looking for serious relationships, dating and friends.
The boy is still living like he was single and looking.
Financial: He is really bad with money and whilst I have tried and tried to help him, whilst he has said he is open to the help and likes the help ... he doesn't listen thru this actions. He works long hours (or more hours) because of his debt yet at the same time he won't do what needs to be done in order to really get rid of it all so that he won't have to work so much.
First of all, you aren't likely to "fix" him. Men marry women thinking that they will never change and women marry men believing that that will change. Both are usually pretty disappointed.
I'm not trying to turn this into a cliche, but you've been together for 7 months, he has at least one difficulty in dealing with money that you will probably not be able to solve until HE wants to change the way he handles money and you have already caught him lying about on-line contact and flirting with other women, which is how you met him to begin with.
Not spending enough time together as a couple mainly due to his work (and sometimes my work)... then him not making "us" a priority (only after his kids, work and himself even).
What happened to his prior marriage (relationship) that resulted in the kids? How long since it ended?
Tell me again why you think this is the right guy for you...
While any of these problems might be able to be solved, it will take commitment and work from him as well as from you in order to accomplish much. Do you think he is ready to make that commitment and do the hard work it will take?
If you want this to work with him, for the financial part see
